Answer: B)

Maria's reasoning: Oil price is expected to increase -> I don't use any oil -> the increase in oil price won't increase my cost of living

A) We'd have to come up with a convoluted assumption that higher gas prices = fewer people buy gas = less funding for public transport = increase in public transport ticket costs to maintain required revenue -> INCORRECT
B) If the transport cost of groceries and essential items substantially increases, then you would expect this increase to be passed onto the consumer -> CORRECT
C) Irrelevant -> INCORRECT
D) If true, would Maria's reasoning still hold (that the increase in OIL PRICE won't increase her cost of living)? Yes. -> INCORRECT
E) Anything given in the prompt is always assumed to be truthful and besides, even if the economists are slightly off, her reasoning would still hold -> INCORRECT

prethinking -- maria assumes i don't directly use oil-- oil prices won't significantly affect my cost of living

weakner--show direct effects of oil prices on the things she buys

A-Tax funding, not maria's cost
B-diesel truck- good cost more- maria pays more
C-WHF irrelevent
D-electricity rises for another reason
E-only supports prediction

Over the coming two months, the price of oil in Esteria is projected to increase by enough to approximately double the price paid by Esterian drivers for each gallon of gasoline or diesel fuel. Maria, who lives and works in a large Esterian city, has no car, commutes on electric-powered public transit vehicles, and uses household power derived from hydroelectricity and natural gas. Since she does not use oil-based fuel in any of her everyday activities, Maria does not expect any significant impact on her own cost of living if the Esterian oil price jumps as projected.

(A) Esteria's public-transit systems, including the one on which Maria makes her daily commute, are funded by a fixed-percentage tax charged on all purchases of gasoline or diesel fuel within Esteria. Mainly about how transport is funded. Maybe maria will stop taking this transport. NO
(B) Groceries and other essential items must be transported into Maria's city on small-to-medium-sized diesel-powered trucks. These type of costs are transferred to consumers by increasing the price of items. Knowingly or unknowingly maria have to pay for these. And this will affect her cost of living. ANSWER

(C) If the price of gasoline climbs as projected, many companies in Maria's city will allow employees who live in the surrounding suburbs to work from home one to two days per week. NO
(D) Newly enacted environmental legislation will increase by one-half the amount that Maria must pay for electrical power. This increase is because of environmental legislation. NO
(E) The economists who have predicted the upcoming increase have been correct in nearly all of their recent predictions concerning the Esterian economy. Irrelevant

Maria does not expect any significant impact on own cost of living despite increase in price of each gallon of diesel/gasoline.

We need to weaken her reasoning.

A) this would increase the funding available for the transit system hence making the per person ticket price cheaper so will have impact on her cost of living. but since we don't know the percentage itself, we can't say if that's going to be significant or not.
B) must be transported suggests strong language which can be used to weaken the argument. groceries & essential items will be bought by her no matter what hence the price hike of diesel will eventually transfer over to end consumer which means her grocery/other essential item expenditure will increase. correct
C) no mention of Maria, we are interested in weakening the argument that oil price hike impacts Maria's cost of living.
D) some other legislation will increase her power bill hence increasing cost of living. but this isn't due to oil price hike rather some other environmental legislation.
E) even if economists are correct, that does not help weaken Maria's reasoning.

We have to make a point that Maria will have to undergo significant impact on her cost of living - keeping in mind what she uses & how can she e impacted indirectly too.

A - she dosen`t purchase gasoline/diesel so unimpacted
B - yes it will make maria pay more. CORRECT
C - not proving our point, opposite
D - incorrect as we are only concerned with oil prices as the cause
E - so what , irrelevant

A- Tax on gasoline is fixed, will not affect maria.
B- Oil price rise- transportation cost rise- grocery price rise- cost of living of maria rise. Hence it weakens
C- Work from home? Out of scope
D- This will increase maria's expenses but not due to rise in oil prices. Trap choice
E- Tells about economists prediction, irrelevant to us.

Premise :
over next 2 months , price of oil in Esteria is expected to increase and its impact will be such that price of each gallon og Gasoline or diesel will be double..

Maria who lives and works in Esteria , has no car and commutes in public vehicle .. house is powered by hydro electricity & natural gas , feels that this impact of oil price will have no significant impact on her own cost of living....


Which of the following, if true, most weakens Maria's line of reasoning?

Weakener type CR


(A) Esteria's public-transit systems, including the one on which Maria makes her daily commute, are funded by a fixed-percentage tax charged on all purchases of gasoline or diesel fuel within Esteria.


this is infact a strengthener as chances are that public transport tariff might get cheap ; incorrect


(B) Groceries and other essential items must be transported into Maria's city on small-to-medium-sized diesel-powered trucks.

this is an alternate reason why cost of living will increase & why it will impact Maria ; correct option


(C) If the price of gasoline climbs as projected, many companies in Maria's city will allow employees who live in the surrounding suburbs to work from home one to two days per week.

this option is not relevant to premise of argument ;in correct option


(D) Newly enacted environmental legislation will increase by one-half the amount that Maria must pay for electrical power.
the option does not address reason on impact on cost of living of Maria ; in correct option


(E) The economists who have predicted the upcoming increase have been correct in nearly all of their recent predictions concerning the Esterian economy.

irrelevant to argument option discuss to , and this does not weaken the conclusion ; in correct option

OPTION B is correct

Premises:
Esteria increased oil prices, Maria lives in Esteria
Maria uses electric based public transport and electric based household power, and stays away for oil fuel in here daily life

Conc says - maria isn't affected significantly by the rise in oil prices

we would have to weaken it by showing Oil prices do impact her

Option A - links Maria with Public Transport which runs on oil prices, which is good so far, we could assume that the public transport might have increased ticket prices and there go Maria getting affected, but it adds in an additional statement that the public transports are funded by the gas tax, so doesn't weaken

Option B - similar concept as A, Groceries and essentials that Maria purchases are delivered by oil-fueled trucks, meaning the delivery charges could have risen to keep up with their fuel costs, so it will impact Maria .... so keep it

C - if Employee stays home, so will Maria, it does save some of her money that she spends public transport, but it doesn't talk about how oil is gonna impact her, her life mostly stays the same with minor saving from transport charges

D - this does impact as the electricity prices goes up, so will Maria cost of living rise, but Oil or Fuel price increase impacting her is not stated here, so OOS doesn't weaken

E - lol option, it talks about economist and their concern on the Esteria economy, it doesn't even talk or touch oil-maria link, so eliminate (unless some deep meaning is behind this, which i am failing to see)

So going with B

IMO B
Since if gasoline price doubles, the groceries & other essential items price will be impacted, this will impact her cost of living
A= I thought it incorrect because esteria public transit systems are funded by a fixed percent tax charged on all purchase of gasoline or fuel, so if gasoline price increases, even if the purchases are less, the fixed % tax deducted will be more and might not impact Maria commute at all
C= If other employees get wfh 1-2 days, this doesnt impact Maria, irrelevant
D=New implemented environment legislation incraesing electical power amout will definitely impact Maria, however I am not clear how this is relevant to the gasoline price increase, hence out
E=Economist predictions are out of scope of the maria's line of reasoning

I was confused earlier between B and D but I chose B as line of reasoning by Maria is that oil prices would not have significant impact on her cost of living. And option B talks clearly about how increased oil prices would impact while option D states a new factor and not oil factor nor the new factor is related to increased oil prices

A) it would not weaken line of reasoning as it is related to government
B) Correct answer reason I told you above
C) this actually tells the scenario what would happen if oil prices increase but nothing to do with Maria's line of reasoning
D) Eliminate - I discussed above
E) it is about being correct in predictions and not weaken Maria's line of reasoning

A. A fuel tax pays for transit. This might affect how much money is spent on transit. It does not clearly show that Marias living costs will go up.

B. That is correct. If food and other things Maria needs are brought to her by trucks that run on diesel then higher fuel prices will make it cost more to transport these things, which can make the things Maria buys cost more. Even though Maria does not use oil herself she can still be affected by this.

C. This talks about people working from home. This is not related to how it costs Maria to live.

D. This makes Marias electricity cost more. The reason for the increase is because of laws that help the environment not because the price of oil went up. So it does not make Marias thoughts, about oil any weaker.

E. This makes what someone said seem likely to be true but it does not show that Marias conclusion is wrong.

Option B is the best answer choice.

A) How the public transit system is funded it out of scope.
B) If the cost of fuel increases then the coresponding increase will drive the cost of groceries also up. Since transportation cost is usually facctored in. Keep
C) Doesn't weaken cause Maria's case wont be affected by this.
D) The argument is about increase in cost because of the jump in fuel prices. While legislation may impact Maria's costs. We dont know whether its caused by the fuel price jump.
E) Again the accuracy of predicions made by the economists wont impact the argument at all

B seems like the best answer. I ll go with B

imo (B)
A - as price increase, people might buying less oil, but as it is fixed percentage tax, it has both indication(decrease due to lesser gallons of oil bought and increase due to increase pricing and therefore increased tax), no
B - Correct; as operational cost increases for essential groceries, it is weakening the claim
C - doesn't effect maria as she doesn't use fuel based commute
D - maria doesn't use state electric power
E - doesn't alter the relationship

A. If the price of fuel goes up the government may get money from taxes.. This does not mean that Maria will have to pay more money for things.

B. That is correct. Food and other important things are brought to stores by trucks that run on diesel. If diesel becomes very expensive stores may increase their prices. So Maria may have to pay money for things even if she does not buy fuel herself.

C. This is, about people working from home. It does not affect how money Maria has to spend on living.

D. The price of electricity goes up because of laws that help the environment not because of the price of oil. So this does not change what Maria says about oil.

E. This makes what she says seem likely to happen but it does not prove that Maria is wrong.

In the above options, Option B is correct.

We need to employ Pre-thinking to come up with possible reasons and answers to the premise and conclusion:

Premise & Conclusion: The price of oil is expected to double. However, Maria uses EV, Hydro & CNG and doesn't expect it to impact her day-to-day life.

Pre-thinking: However, if the oil price jumps, it may have a ripple effect on the entire economy or others that don't necessarily use EV, Hydro & CNG may be adversely affected and if Maria gets something from them, then in-turn she will be affected by it. Or it may lead to inflation, and affect her.

Options:
A - If it's a fixed % charge, then how much gasoline or price of gasoline doesn't matter. The govt. still takes a fixed cut despite the price increase.
B - B hits the nail on the head in terms of pre-thinking. We can see that if the trucks and vehicles that bring groceries and other essentials run on diesel fuel which will be impacted by the oil prices doubling, then transport becomes more expensive. Accordingly, to offset the transport price increase, the goods transported, i.e., the groceries will also increase in price. This will affect Maria. Hence, this tallies with the pre-thinking and is the correct option.
C - Irrelevant. Whether they are allowed to WFH or not doesn't explain the effect of 2X on the economy.
D - Out of scope. We are not on some new legislation.
E - Again out of scope. Just because economists prediction may come true doesn't help explain why Maria's life may get affected when the oil prices increase..

Hence, the correct answer is B

If maria doesn't use oil her cost of living will not be impacted if oil price jumps. Seems like ignorance of any passive effects.

Evaluating options:
A. Esteria's funding system with tax and all doesnt relate to the cost of living. Eliminate.
B. Diesel powered trucks consumes oil which will increase prices of groceries Fits the direct reason and a possible answer.
C. Working from home is irrelevant and doesn;t attack the conclusion. Eliminate
D. Electrical power prices increase seems to be because of legislative rules and not because of oil. Eliminate.
E. Future prediction keeping everything intact doesn't attack the conclusion. Eliminate.

IMO Ans is B
Bunuel
Over the coming two months, the price of oil in Esteria is projected to increase by enough to approximately double the price paid by Esterian drivers for each gallon of gasoline or diesel fuel. Maria, who lives and works in a large Esterian city, has no car, commutes on electric-powered public transit vehicles, and uses household power derived from hydroelectricity and natural gas. Since she does not use oil-based fuel in any of her everyday activities, Maria does not expect any significant impact on her own cost of living if the Esterian oil price jumps as projected.

Which of the following, if true, most weakens Maria's line of reasoning?

(A) Esteria's public-transit systems, including the one on which Maria makes her daily commute, are funded by a fixed-percentage tax charged on all purchases of gasoline or diesel fuel within Esteria.

(B) Groceries and other essential items must be transported into Maria's city on small-to-medium-sized diesel-powered trucks.

(C) If the price of gasoline climbs as projected, many companies in Maria's city will allow employees who live in the surrounding suburbs to work from home one to two days per week.

(D) Newly enacted environmental legislation will increase by one-half the amount that Maria must pay for electrical power.

(E) The economists who have predicted the upcoming increase have been correct in nearly all of their recent predictions concerning the Esterian economy.
