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 hostsduring their life cycles
OA: B
I would like to ask what's wrong with all the options.
Also, FOR part and IN part, what's the differences between these 2?
is it because the meaning is different??
thank u so much!
