How to identify Tone questions: Tone is feeling, not thinking. Look for emotion
What is the author’s attitude toward . . . ?
Which of the following best describes the author’s feelings toward . . .
How to tackle them: Look for adjectives in the passage that describe
attitudes, or types of emotional response. Also, remember the tone must be consistent with the main idea. Look
for buzzwords, such as “jubilant,” “depressed,” “extraordinary,” etc. The GMAT is too academic to have very intense emotions appear in passages; hence, adjectives that are extreme in their emotion usually can be eliminated. Try this:
Which of the following best describes the author’s feelings towards gentrification?
The author probably is not outraged or exhilarated about the subject. Both of
these adjectives are extreme and would warrant much stronger language than what commonly appears in GMAT passages. On the other hand, "indifference" is probably not accurate either, as it implies too little emotion: if the author doesn't care at all about the topic, why would he write a passage about it? "Acceptance" and "suspicion" are much more moderate feelings, so it's likely that either (D) or (B) is the right answer. Similar to main idea questions, tone
questions look for answers that fit somewhere in the middle: neither too hot nor too cold.
