Question

the leaf insect, easily mistaken for a real ______ maintains a constant wobble as part of its illusion. which choice completes the text so that it conforms to the conventions of standard english? choose 1 answer: a leaf, b leaf c leaf— d leaf;

Explanation:

The sentence structure here is a simple one where "a real leaf" is a noun phrase acting as the object of "mistaken for". There is no need for a comma, em - dash, or semicolon here. A comma would introduce an unnecessary pause, an em - dash is used for emphasis or to set off a clause, and a semicolon is used to separate two independent clauses. So the correct choice is the one with just "leaf" without any punctuation.

Answer:

B. leaf
