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 become 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 cycle
(E) parasite's hosts, freshwater snails which become their hosts during their life cycles
My question is not regarding the underlined, but rather the Non-Underlined part that I have highlighted. Why do we need an "it" to refer back to Schistosomiasis when we clearly know that we are talking about Schistosomiasis. On several occasions GMAT has made it clear that such type of pronoun reference is considered redundant. Seems like GMAT is violating its own rule..unless I am missing something here
