How would you see the usage of that & which in this question.
in Statement A, B - that is used
in C, D, E - which is used.

can they be used interchangeably?

I quietly mentioned the issue of that vs. which in answer choices (C), (D), and (E), but I deliberately didn't say much about it. :-)

Technically speaking, "that" is an essential modifier -- in other words, we wouldn't fully understand the meaning of the sentence without it -- and "which" is a non-essential modifier, meaning that it just provides some extra information. In general, modifiers beginning with "which" usually follow a comma. But unless they're part of a larger list, modifiers beginning with "that" usually do not follow a comma. Here, have a couple of examples:

  • The GMAT book that is on the table is useless. --> The phrase "that is on the table" is an essential modifier, so the sentence implies that you wouldn't know exactly which GMAT book is useless if I didn't include the modifier. In other words, the sentence implies that there are some other books around -- maybe in the refrigerator, or on the bookshelf, or wherever -- and you need me to specify that the one on the table is the useless one.
  • The GMAT book, which is on the table, is useless. --> Now "which is on the table" is just extra information. The sentence implies that there's only one GMAT book around, and it just happens to be on the table. But without the non-essential modifier, you'd still be able to identify the useless book.

The trouble is, either sentence is completely fine. They just mean slightly different things. In practice, it's really hard for the GMAT to test the distinction between essential and non-essential modifiers, and it's rarely -- if ever -- the deciding factor in official questions. Notice that you can absolutely get to correct answer on the schistosomiasis question without giving any thought to the difference between "which" and "that." And that's why I didn't say much about it in the explanation above. :)

But for what it's worth: yeah, "which" isn't a great choice in (C), (D), and (E), since "which" needs to be preceded by a comma, and it seems like the phrase "which become the parasite's hosts" is essential to the meaning of the sentence -- so it probably should start with "that" instead of "which." But in all three of those answer choices, there are arguably more significant issues.

I hope this helps!

(A) the freshwater snails that are the parasite's hosts for part of its life cycle - Correct

(B) the freshwater snails that are the parasite's hosts in part of their life cycle

(C) freshwater snails which becomes the parasite's hosts for part of its life cycles - SV Number agreement error and also ',' is missing before which

(D) freshwater snails which become the hosts of the parasite during the parasite's life cycles - ',' is missing before which

(E) parasite's hosts, freshwater snails which become their hosts during their life cycles - above errors + change in meaning



As we know that all pronoun refers to the one antecedent not different one, 'it' is non underlined part refers to Schistosomiasis where as 'its' in underlined part refers to parasite. therefore A can not be right answer,???

please explain.

robu , from what source did you get the rule that there can be only one pronoun that must always refer only to the main subject of the main clause?

A pronoun needs to refer to the most logical antecedent -- to the antecedent that makes sense. In this case that antecedent is the parasite.

Complex sentences can and often do have more than one noun and more than one pronoun. The pronouns must be logical and must be parallel in number and gender to the noun.

It sounds as if you might believe something different. That's not accurate. I can see why you might think that were the rule, but it isn't. Answer A is correct.

Hope that helps:-)

A pronoun needs to refer to the nearest and most logical antecedent. In this case that antecedent is the parasite.

Complex sentences can and often do have more than one noun and more than one pronoun. The pronouns must be logical and must be parallel in number and gender to the noun.

It sounds as if you might believe something different. That's not accurate. I can see why you might think that were the rule, but it isn't. Answer A is correct.

I was just about to say the same thing, but generis beat me to it! Nice post. :)

generis's post is spot-on: there is no rule -- on the GMAT or in real life -- that states that you can't have multiple pronouns in a sentence, referring to different referents. In general, the GMAT wants you to pick the answer that most clearly conveys the intended meaning, and pronouns will USUALLY refer to the most recent potential antecedent. But even that isn't an absolute rule: in some cases, the GMAT tolerates some pronoun ambiguity when there are no better options available (more on that in this video. And there's definitely nothing inherently wrong with using the same pronoun twice in a complex sentence, as generis explained.

I hope this helps!

POE: 1. That Vs. Which : "that" is an essential modifier -- in other words, we wouldn't fully understand the meaning of the sentence without it -- and "which" is a non-essential modifier, meaning that it just provides some extra information.
Since, here “which” is not preceded by comma ,and it is providing essential information about the “freshwater snails” hence, “THAT” should be used. C.D & E are out.
POE 2: “IT” Vs. “Their”: Since pronoun IT & They are referring back to “a parasitic worm”, which is singular. Therefore, “IT” has to be used. B & E are out.
POE 3: Use of “THE”: The is used to be SPECIFIC about the information i.e. it is “Freshwater snails” that play host role for Parasite. Therefore usage of “The” is required. C.D & E are out.
A is the answer.

Hello anuj04,

That's a very interesting way of performing the PoE. Good work there. :thumbup:

However, I would just like to add that I would never reject an answer choice just because which is not preceded by a comma. In fact I would never reject or select an answer choice only on the basis of the usage of a particular punctuation mark.

I would find at least one deterministic error to reject answer choices. For example:

Choices B and E are incorrect for the incorrect usage of plural pronoun their to refer to singular parasite's.

Choice C is incorrect for the SV number agreement error.

Choice D is incorrect for the incorrect usage of plural life cycles because this phrase illogically suggests that the parasite has multiple life cycles.



Hope this helps. :-)
Thanks.
Shraddha
