While working at Zoo,
Michelle saw a monkey, climbing a tree and carrying a baby.(A) Michelle saw a monkey, climbing a tree and carrying a baby. -
here, the 3 verbs (saw, climbing, and carrying) are in parallel- This kind of a structure effectively allows us to assume that it is the same subject that is performing each of the three verb actions. In the context of this sentence, this universal subject idea does not make sense. Hence, eliminate (A).
(B) Michelle saw a monkey, climbing a tree and that carried a baby. -
Has a parallelism error here. Hence, eliminate (B).
(C) Michelle, carrying a baby, saw a monkey climbing a tree. -
(C) conveys that it was michelle who was carrying the baby, not the monkey. (C) therefore changes the intended meaning of the sentence. Hence, eliminate (C).
(D) Michelle saw a monkey climbing a tree and carrying a baby. -
the 2 verbs in parallel are 'climbing' and 'carrying'; both these verbs are commanded by the same subject 'monkey'. This makes complete sense. hence, (D) is the right answer choice here.
(E) Michelle saw a monkey with a baby, climbing a tree. -
the -ing word 'climbing' tries to modify the 'baby' as if to convey that it is the baby that tried to climb the tree, and not the 'older' monkey. This changes the intended meaning of the sentence. Hence, eliminate (E).
