Solution

Modifiers + Pronoun

A and D: “which” incorrectly modifies “United States”.
B: “it” incorrectly modifies “Iran”. “Iran” neither is “complex” nor does it “depend on…”
C: “they” does not have an antecedent.
E: “task” refers to “Ms Wright’s” attempt to “get inside Iran” and to “understand…”. Hence, E is the best choice.
