There is no consistent rule considering gerund v. infinitive. Instead, the determination is normally made by taking the grammatical context into question. Remember, a gerund is a noun, so it will be used when the reference is to a person, place or thing. Conversely, verbs are used with the reference is to an action.

In terms of -ing verb forms v. infinitive, the determining factor is normally parallel construction. Be certain to carefully read/analyze the non-underlined part of the sentence; most frequently, this is where clues to the proper construction will be located.

In the sentence at hand, a scrub jay can remember one thing, and tendsnot to bother with another. Additionally, the pronoun it in choice E lacks an antecedent.

The correct answer is D

Tend not bothering to do表示的是不耐烦做某事，因此意思是也不对
