its in that are the parasite's hosts for part of its life cycle refers to parasite's. So, effectively, this portion says -- ...the the freshwater snails that are the parasite's host for part of the parasite's life cycle.

Cheers! :)


Thanks neetis5! Yes, "its" is a possessive pronoun referring to the possessive "parasite's".

Question # 92 from the Verbal Review - 2nd Edition of the Official Guide - Sentence Correction (page 310)

Schistosomiasis, a disease caused by a parasitic worm, is prevalent in hot, humid climates, and it has become more widespread as irrigation projects have enlarged the habitat of the freshwater snails that are the parasite's hosts for part of its life cycle.

A. the freshwater snails that are the parasite's hosts for part of its life cycle
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
D. freshwater snails which become the hosts of the parasite during the parasite's life cycles
E. parasite's hosts, freshwater snails which become their hosts during their life cycles

[Reveal] Spoiler:
I said B, which I can see how it's wrong because after reading the answers I understood they meant the life cycle is of the parasite, not the host - so my mistake was more in the meaning of the sentence rather than grammar.

The right answer is A - my questions is this: in MGMAT sentence correction book I remember reading that one should be very careful using a pronoun of a possessive term and that it's usually incorrect. So in A, they are saying that "its" refers to parasite's - this seems wrong. Does anyone else agree? Or am I misunderstanding something? To me it is not clear what "it" refers to because the term parasite is in a possessive term.


Schistosomiasis, a disease caused by a parasitic worm, is prevalent in hot, humid climates, and it has become more widespread as irrigation projects have enlarged the habitat of the freshwater snails that are the parasite's hosts for part of its life cycle.

A. the freshwater snails that are the parasite's hosts for part of its life cycle
Seems ok ... (its referring to Parasite - so no pronoun number agreement issue)

B. the freshwater snails that are the parasite's hosts in part of their life cycle
"their" is incorrect since its plural it now refers to plural antecedent "snails" which is illogical

C. freshwater snails which becomes the parasite's hosts for part of its life cycles
"becomes" is singular - we need plural verb become for plural subject snails
Also, "life cycles" - plural- as in each parasite has more than one life cycle !!! Incorrect

D. freshwater snails which become the hosts of the parasite during the parasite's life cycles
same as Option C (lifecycles)

E. parasite's hosts, freshwater snails which become their hosts during their life cycles
"their" - plural pronoun does not have an antecedent ...we need an antecedent for "a parasite worm" which is singular and hence the antecedent shall also be singular. Incorrect

This question hinges whether parasite's can act as Subject .
Yes they can so A is the correct answer.

A is the correct choice - The sentence is clear with all pronouns and verbs in agreement.
