My answer is (D). We use present participle to indicate the end results of the actions previously listed. But what are the actions and what their results?

The sentence mentions the following phenomena:
(1) The rains and sudden dip in temperature
(2) Increase in the circulation of viruses
(3) Decrease in the immunity of the body
(4) Increase in the cases of fever and cough and cold.

BTW, I do not like the construct of "fever and cough and cold" as it uses too many and's. But there is no split for it.

So, I believe the most logic sequence is that
(1) --> (2) and (3) --> (4)
BUT, why can't
(1) --> (2) --> (3) and or --> (4)?
We are no expert in medical field. We do not know if (3) is direct result of (1), or (2). For some people (well, I assume we are talking about the fever and cough and cold of human beings), (1) might cause increase in the immunity briefly, with or without (2).

So, this questions gets me thinking...

But (D) makes most sense, I finally decided.

Correct answer is D.
Answer choice D correctly combines the two effects (increase in circulation of viruses and decrease in the immunity of the body) of the cause (the rains and sudden dip in temperature) in a parallel structure.
Also uses the correct S-V pair, increase and decrease, for the compound subject Rains and sudden dip in temperature.

A prepositional phrase in the beginning of a sentence will modify the subject and the verb of the sentence, as any other adverbial modifier does. Here with the rains and sudden dip in temperature explains how the circulation of viruses increases. In other words, rains and temperature drop facilitate the increase of the virus circulation.

Another adverbial modifier at the end of the sentence decreasing immunity... and increasing the cases... will modify the closest verb and its subject in the preceding sentence. In other words, the increase in virus circulation results in the decrease of immunity and the increase of some cases.

Original meaning: rains and temperature drop leads to increased virus circulation -> increased virus circulation leads to the decrease of immunity and the increase of some cases. A has no any error. I will keep it.


The most blatant error is the subject-verb disagreement. The rains and sudden dip in temperature is a compound noun and thus should be followed by a plural verb increase. Additionally, B changes the original meaning, erroneously suggesting that rains and temperature drop resulted in the decreased immunity, while originally that’s the increased virus circulation what caused decreased immunity.


The most blatant error is the subject-verb disagreement. The rains and sudden dip in temperature is a compound noun and thus should be followed by a plural verb increase. Again, the original meaning is changed. The rains and sudden dip in temperature don’t increase the cases of fever and cough and cold.
Cause decrease is less concise than decrease.


Cause increase is less concise than increase. Again, the original meaning is changed. The rains and sudden dip in temperature don’t cause decrease in the immunity of the body.


The most blatant error is the subject-verb disagreement. Cause increase is less concise than increase. Again, the original meaning is changed. The rains and sudden dip in temperature don’t cause increase in the cases of fever and cold and cough.

Hence A

Rule: Cause and Effect (One action leading to other), Agreement

A. With the rains and sudden dip in temperature, the circulation of viruses increases, decreasing immunity of the body and increasing the cases of fever and cough and cold. - Increase
B. The rains and sudden dip in temperature increases the circulation of viruses, decreases immunity of the body, and increases the cases of fever and cough and cold
C. The rains and sudden dip in temperature cause decrease in immunity of the body and increases the cases of fever and cough and cold, increasing the circulation of viruses
D. The rains and sudden dip in temperature cause increase in the circulation of viruses and decrease in the immunity of the body, increasing the cases of fever and cough and cold. - Agreement (Plural) & Cause & Effect in place - Correct
E. The rains and sudden dip in temperature causes increase in the cases of fever and cold and cough and decrease in the immunity of the body, increasing circulation of viruses.

IMO Option D

the choices introduces several scenarios, but only one is logic:
rain + sudden low temperature --> increase virus circulation + reduce immunity ---> increase cases of fever & cough

A. With the rains and sudden dip in temperature, the circulation of viruses increases, decreasing immunity of the body and increasing the cases of fever and cough and cold.
it seems a good contender but there are several subtle alterations in meaning,
(1) "With" can only be used to modify the doer of the action. "circulation" is not the doer of its increase, but the "increased circulation" is the result of the "rains and sudden dip in temperature".
(2) "decreasing", a participial phrase modifying the preceding clause, means that the circulation of virus decreases the immunity, showing an irrelevant cause-effect relationship.

B. The rains and sudden dip in temperature increases the circulation of viruses, decreases immunity of the body, and increases the cases of fever and cough and cold.
increases/decreases: clear SV agreement flaw.
meaning problem: The rains and sudden dip in temperature ... increase the cases of fever and cough and cold? rain and low temperature don't cause fever and cough by themselves, but the viral infection to low immunity body.

C. The rains and sudden dip in temperature cause decrease in immunity of the body and increases the cases of fever and cough and cold, increasing the circulation of viruses.
increases: clear SV agreement flaw.
increasing the circulation of viruses: a meaning flaw, as low immunity and increased cold and cough can't be the reason for increased viral circulation (reversed logic)

D. The rains and sudden dip in temperature cause increase in the circulation of viruses and decrease in the immunity of the body, increasing the cases of fever and cough and cold.
correct, representing the logical cause effect mentioned at the beginning of the explanation, and show correct parallelism and SV agreement

E. The rains and sudden dip in temperature causes increase in the cases of fever and cold and cough and decrease in the immunity of the body, increasing circulation of viruses.
causes: clear SV agreement flaw.
meaning problem: the same reversed logic discussed in C

D is the one

This question has a split in logics.
Logically, rains and sudden dip in temperature leads to two things:
1) increase in circulation of viruses
2) decrease in immunity
The above two in turn lead to increase in cases of fever, cold and cough.

The only option that captures this logic is option D.

With the rains and sudden dip in temperature, the circulation of viruses increases, decreasing immunity of the body and increasing the cases of fever and cough and cold.

Meaning:

'with' prepositional phrase starting the sentence makes it a little bit confusing to find the intended meaning, but let's try to think it over

'the circulation' cannot have own 'rain and temperature drop', most probably 'rain and temperature drop causes circulation of viruses.
Then this situation decrease immunity and increase fever and cough cases or vise versa.

More or less the meaning is clear, but we need to search the answer choice with clear and concise meaning.

Errors:

To me only error of this sentence is 'with' opening prepositional phrase, it doesn't make any sense.

If you have doubts about double 'and' parallelism:

POE:

A can be eliminated straight away:

A. With the rains and sudden dip in temperature, the circulation of viruses increases, decreasing immunity of the body and increasing the cases of fever and cough and cold.

B. The rains and sudden dip in temperature increases the circulation of viruses, decreases immunity of the body, and increases the cases of fever and cough and cold.
(we have SV agreement error, Plural "The rains and sudden dip in temperature" don't agree with Singular "increases", "decreases", "increases", also all these three verbs connected in ONE list, and this construction makes them equal in meaning - which is wrong)

C. The rains and sudden dip in temperature cause decrease in immunity of the body and increases the cases of fever and cough and cold, increasing the circulation of viruses.
(here we also have SV agreement error, Plural "The rains and sudden dip in temperature" don't agree with Singular "increases", moreover last v-ing modifier is wrong here, it illogically mixed up cause and effect)

E. The rains and sudden dip in temperature causes increase in the cases of fever and cold and cough and decrease in the immunity of the body, increasing circulation of viruses.
(here we also have SV agreement error, Plural "The rains and sudden dip in temperature" don't agree with Singular "causes", moreover last v-ing modifier is wrong here, it illogically mixed up cause and effect)

D. The rains and sudden dip in temperature cause increase in the circulation of viruses and decrease in the immunity of the body, increasing the cases of fever and cough and cold.

Generally question tests meaning and SV agreement, if you are careful with details, you will be okay.

D is the answer

With the rains and sudden dip in temperature, the circulation of viruses increases, decreasing immunity of the body and increasing the cases of fever and cough and cold.

A. With the rains and sudden dip in temperature, the circulation of viruses increases, decreasing immunity of the body and increasing the cases of fever and cough and cold.
B. The rains and sudden dip in temperature increases the circulation of viruses, decreases immunity of the body, and increases the cases of fever and cough and cold.
C. The rains and sudden dip in temperature cause decrease in immunity of the body and increases the cases of fever and cough and cold, increasing the circulation of viruses.
D. The rains and sudden dip in temperature cause increase in the circulation of viruses and decrease in the immunity of the body, increasing the cases of fever and cough and cold.
E. The rains and sudden dip in temperature causes increase in the cases of fever and cold and cough and decrease in the immunity of the body, increasing circulation of viruses.

This question is best tackled with a meaning-based approach.
Let's first understand what the question statement is trying to tell us.
With the rains and sudden dip in temperature, the circulation of viruses increases, decreasing immunity of the body and increasing the cases of fever and cough and cold.

Sage advice: whenever there is a ",ing" in a sentence, your first motive should be to check it thoroughly.
What this sentence is trying to say is - Increase the circulation of viruses causes - decrease in the immunity of the body and increase in the cases of fever and cough and cold. WAIT! that doesn't make sense. How can increase in no. of viruses cause your immunity to decrease??
SO now we have found our ERROR.
Also, if you look closely, you will see that there is a subject-verb agreement error too.
the rains and sudden dip in temperature, the circulation of viruses increases
More apparent now?
RAINS AND sudden dip in temp is plural as opposed to the singular INCREASES.

Now, at this point of time you can go ahead with either error and start POE. I personally would like to go with the meaning approach in this question since the big meaning difference.

[A] as discussed above.

(B). I found the meaning to be fine, so had to use the second error to eliminate this one.
The rains and sudden dip in temperature [/b]increases[/b] the circulation of viruses, decreases immunity of the body, and increases the cases of fever and cough and cold. - Should be INCREASE.

[C] This statement implies that the increase in the circulation of virjus is due to decrease in immunity of the body and increases the cases of fever and cough and cold. COMPLETELY WRONG

[D] CORRECT. Implies The rains and sudden dip in temperature cause increase in the circulation of viruses and decrease in the immunity of the body which leads to an increase the cases of fever and cough and cold. PERFECT

[E] exactly the inverse of [A]. The decrease in immunity leads to increase in no. of virus. WRONG!
