This was a very very tough question with a very subtle detail. It may be even too subtle but it illustrates importance of reading attentively and precisely.
Thank you,
BB.

Official Explanation by examPAL:

What’s important to understand in the argument is that the mayor claims that the population increase won’t affect the existing recreation areas, not only recreation areas in general.

Therefore, (A) and (B), which might seem relevant since they discuss new recreation areas, are not relevant – since they don’t address the concern that the exiting areas will be harmed.
(C) is completely irrelevant.
(D) directly addresses the issue: if the new housing replaces existing housing, it won’t affect existing recreation areas.
(E) is irrelevant and weakens the argument: it describes a negative effect of the population growth.

We need to find a reason, why the recreational areas will not be affected even after an increase in population.

(A) By attracting more new citizens, Dorthhampthon's municipality will be able to increase its budget for the development of recreation areas----- This would suffice as more money would be invested for the areas

(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings--- we are concerned about areas in city's center

(C) Dorthhampthon's ratio of park area per resident is about half that of similar cities in the region.------ irrelevent

(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes------ irrelevent

(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure------ then it could also cause challenges to recreational areas

Correct
(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings.
The claim is about the existence of the current recreation areas while this is about the development of new areas, so this is irrelevant.
(C) Dorthhampthon's ratio of park area per resident is about half that of similar cities in the region.
Population amount of other cities would not affect the existent of current recreation areas
(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes.
If anything, this would be the weaken the mayor's office claim as it would threaten the existence of current buildings.
(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure.
This would also weaken the mayor's office's claim

(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure.

Prethinking :
the mayor claim's that the expected growth won't threaten the existence of recreation area.
Hence information of a separate provision made by the city to incorporate such a rise in population can help strengthen the argument.
POE:
A) By attracting more new citizens, Dorthhampthon's municipality will be able to increase its budget for the development of recreation areas. Irrelevant : as the argument talks about the area and not funds
(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings. Wrong :Claims are made of the existing areas and not the new ones
(C) Dorthhampthon's ratio of park area per resident is about half that of similar cities in the region.Irrelevant : as no comparison is made with the other cities
(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes. Perfect as new houses replace the old one having lower buildings--> Correct
(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure. Irrelevant weakens the claim

Option D

The population of Dorthhampthon is expected to grow at an average rate of 6 percent a year in the coming decade. Many of Dorthhampthon’s residents raised concerns regarding the effect of this growth on the recreation areas in the city's center, yet the Dorthhampthon mayor's office claims that such growth will not threaten the existence of any of these.

Which of the following, if true, will most strengthen the claim of the mayor's office?

(A) By attracting more new citizens, Dorthhampthon's municipality will be able to increase its budget for the development of recreation areas. - Now if more new citizens are attracted, & the municipality budget is increased for the development of recreation areas (residents are mainly concerned about the fact that increase in population will lead to threaten the existence of recreation areas in the CITY's CENTER).; the mayor is claiming that no such threat is there & the increased budget in this regard will help the city authority to develop the recreation area that can afford the increased population growth - Hence CORRECT)
(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings. - But the residents are concerned about the recreation areas in the city's center, not in the surrounding of the city, if the municipality intends to increase the city's jurisdiction, this statement is nowhere related to the current argument in hand;
(C) Dorthhampthon's ratio of park area per resident is about half that of similar cities in the region - This in turn weakens the argument as already ratio of park area per resident is much lower compared to that of similar cities in the region, then increased population will lead to worse result.
(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes. - Who cares about the new housing projects, we are concerned about the future of recreational area.
(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure - Again if the city's infrastructure is challenged then the residents prediction may be true that the authority cannot handle the existing infrastructure of recreation area, thus weakening the mayors claim.

B- out of scope. We are talking about city centre recreation areas, not the recreation areas in its surroundings.

C-Out of scope. Doesn't matter what's the ratio in other areas.

D- we need to be focused on recreation areas. Housing infra is not important

E- same as D

The population of Dorthhampthon is expected to grow at an average rate of 6 percent a year in the coming decade. Many of Dorthhampthon’s residents raised concerns regarding the effect of this growth on the recreation areas in the city's center, yet the Dorthhampthon mayor's office claims that such growth will not threaten the existence of any of these.

This is a fairly simple question. The stem revolves around The population of Dorthhampthon is expected to grow and the effect of this growth on the recreation areas in the city's center, yet the Dorthhampthon mayor's office claims that such growth will not threaten the existence of any of these.
We need a possible strengthen that claims are correct.

Which of the following, if true, will most strengthen the claim of the mayor's office?

(A) By attracting more new citizens, Dorthhampthon's municipality will be able to increase its budget for the development of recreation areas.
This is the case of maybe, maybe the city is able to attract the new citizens, maybe not. Also to note is that with an increase in the new citizens, more space would be needed.
Hence this is incorrect.

(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings.
Yes, this is the correct answer. New space will be allocated for parks and recreation.
It strengthens.

(C) Dorthhampthon's ratio of park area per resident is about half that of similar cities in the region.
We cannot afford comparison, because there could be other factors in play.
Hence this is incorrect.

(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes.
We are not sure of the result. Will it lead to more space or less space? That is still a question mark.
Hence this is incorrect.

(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure.
This in fact supports the residents claim. This is a weakener.
Hence this is incorrect.

For the above-stated reasons, Answer B is correct.

Many of Dorthhampthon’s residents raised concerns regarding the effect of this growth on the recreation areas in the city's center, yet the Dorthhampthon mayor's office claims that such growth will not threaten the existence of any of these.

We need to find a reason supporting the claim that population growth in the city "will not threaten the existence" of the recreation areas.
We want the current recreation areas to remain recreation areas.

Which of the following, if true, will most strengthen the claim of the mayor's office?

(A) By attracting more new citizens, Dorthhampthon's municipality will be able to increase its budget for the development of recreation areas.
If the budget is higher, new areas could be built and existing areas could be improved.
While this sounds good, a higher budget doesn't directly protect the space.

(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings.
This option discusses the development of new areas, not the protection of existing areas. I think that disqualifies this answer choice.

(C) Dorthhampthon's ratio of park area per resident is about half that of similar cities in the region.
This does nothing for the argument that population growth will not threaten the existence of the recreation areas.

(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes.
Looks good. By stating that the growing population will be housed on the current building area (no new area will need to be converted to building area), this answer choice supports the claim that the existence of the recreational areas is not threatened. If the growing population can be housed without additional building area, the current recreational area is probably safe. While this does depend on taking "existence" quite literally, this is the best choice here.

(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure.
This does not offer any support for the argument that population growth will not threaten the existence of the recreation areas. In fact, the answer choice probably weakens the city's argument.

Conclusion of residents: Population growth will have an effect on recreational areas in the city's center
Conclusion of Mayor's office: Population growth will NOT have an effect on recreational areas in the city's center

We need to find a reason why the recreational areas in the city's center will not be affected

(A) By attracting more new citizens, Dorthhampthon's municipality will be able to increase its budget for the development of recreation areas.
Will this development be in the city's center? We don't know - Eliminate

(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings.
Will these areas be in the city's center? We don't know - Eliminate

(C) Dorthhampthon's ratio of park area per resident is about half that of similar cities in the region.
We are worried only about Dorthhampthon's city center - Out of scope

(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes.
This says that new housing projects are coming up in the city center where buildings are already existing and so will not have an effect on the recreational areas - Keep

(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure.
Out of scope

(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings. we do not know the certainty of this one, so we can discard it
(C) Dorthhampthon's ratio of park area per resident is about half that of similar cities in the region. irrelevant, we do not know anything about other similar cities
(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes. irrelevant

the mayor cliams that the existing areas will not be effected by the polulation growth. prethinking, either the parks might be maintained better or more parks can be constructed.
However, constructing more parks does not gaurantee that the people might go to the newly constructed parks. so the only option would be to see if the increased maintenance is possible.
so A does exactly that and right choice in my opinion.
C,D and E are again out of scope

We have to find a statement that supports the mayor’s claim that the growth in population will not threaten the EXISTENCE of existing recreation areas in the city center. So we need something to ensure that the recreation areas will still be kept in their current places even when the population increase.

(A) By attracting more new citizens, Dorthhampthon's municipality will be able to increase its budget for the development of recreation areas.
—> this sounds nice, but increasing budget doesn’t ensure that the recreational areas will be remained in the current places. WRONG

(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings.
—> this definitely hurts the mayor’s statement as it may implies removing parks and recreation to surrounding areas -> threaten the existence of recreation IN city center. WRONG

(C) Dorthhampthon's ratio of park area per resident is about half that of similar cities in the region.
—> irrelevant. This has nothing to do with the existence of recreation areas. WRONG

(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes.
—> well this is like what we are looking for. Replacing old and lower building with new one will assure that new citizens have shelter without taking the place of existing recreation grounds to build new houses.

(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure.
—> opposite. This hurts the argument of the mayor.

So I think the answer is D

its not clear if the budget increase will help the recreational areas.

(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings.
strengthen the argument. this will increase the areas therefore the increase in population does not affect the recreational areas.

(C) Dorthhampthon's ratio of park area per resident is about half that of similar cities in the region.
does nothing to strengths the aregument.

(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes.
Weakens the argument. this may affect the recreational area as well.

(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure.
Weakens the argument.

Though population of Dorthhampthon is increasing but mayor claim's that this wouldn't effect existence of recreation areas.
Option A helps in strengthening this fact that more citizens would increase budget and hence help in the development of recreation areas.

Hence A

First, we have to understand the concerns of the residents regarding the recreation areas. Their concern is about the crowdedness and population pressure on these areas.

(A) By attracting more new citizens, Dorthhampthon's municipality will be able to increase its budget for the development of recreation areas.
Irrelevant!, The concern was not about the budget or the money allocated or the development of these areas. Money won't help when the recreation areas are crowded.

(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings.
Helpful : It means that the increased population will be compensated by similar increase in the parking areas and the recreation areas in the city, ensuring that the recreation areas are not overcrowded

(C) Dorthhampthon's ratio of park area per resident is about half that of similar cities in the region.
Irrelevant! comparing with other cities doesn't help to conclude anything, plus it doesn't tell anything about what will happen in the future when the population increases

(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes.
Worse!: This means that the citizens near the recreation areas will increase and the concerns will be a reality.

(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure.
Bad news!: that exactly what the citizens fear of

B

(A) By attracting more new citizens, Dorthhampthon's municipality will be able to increase its budget for the development of recreation areas.
the population will grow by 6% per year and this also means that there will be 6% childern be born and ther is nothing that says that they will attract new citizens from other places. long shot so not preferd choice.

(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings.
If the city is able to create new parks and recreational places then the increased load of population can be supported by the new infra and the load on the city center will not be affected at large.
[color=#ff0000](C) Dorthhampthon's ratio of park area per resident is about half that of similar cities in the region.
[/color]

The ratio of park per resid is half of that of he other city but it still has some impact on the centers recreational areas even if it is small.
this choice is relevant but is not precisely addressing the issue.

(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes.
housing project will replace other older complexes and not the recreational areas.

(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure.
this supports he citizens concern and not the claim by the mayor.

Claim of Mayor's office: City's population growth of 6 percent a year in the coming decade will not threaten the existence of the recreational areas in the city's centre.

Which of the following, if true, will most strengthen the claim of the mayor's office?

(A) By attracting more new citizens, Dorthhampthon's municipality will be able to increase its budget for the development of recreation areas
This statement mentions about increasing budget for development of recreational areas but does not ensure that population increase will not threaten the existence of the recreational areas in the city's centre. Incorrect

(B) Dorthhampthon's municipality intends to increase the city's jurisdiction, allocating new areas for parks and recreation in its surroundings.
Mayor's office claim is about not threatening the existence of the recreational areas in the city's centre. It is not about city's surroundings. Incorrect

This statement does not mention anything about not threatening the existence of the recreational areas in the city's centre. Incorrect

(D) The new housing projects in central Dorthhampthon are planned to replace lower buildings in older complexes.
This statement mentions that new housing projects in city's center are planned to replace lower building in older complexes so that new developments will not threaten the existence of the recreational areas in the city's centre. Correct

(E) Annual population increase of 6 percent a year poses a significant challenge to the city's infrastructure.
This statement does not mention anything about not threatening the existence of the recreational areas in the city's centre. This statement in fact weakens mayor's office claim. Incorrect

IMO D
