Tips: Listen for the idea the speaker keeps coming back to at different points.

Why the other options are wrong:

• Personal stories should be set aside until a formal study supports them.: The speaker says personal experience can begin an inquiry. So stories are not set aside.
• Personal stories are enough to rely on when a habit is cheap to try.: A cheap habit can be tested personally. But the speaker says a story should start an inquiry, not end it.
• A habit should be tried for two weeks before anyone judges its value.: Two weeks was only the length of the practice exercise. The speaker does not give it as a general rule.

Correct Answer: Stories that turn one person's result into a promise for anyone.

Why this is correct: The sceptical group is especially concerned when a speaker moves from 'this helped me' to 'this will transform anyone'.

Tips: Keep each worry linked to the group that raises it.

Why the other options are wrong:

• Stories that leave out how much a method costs to follow.: Cost comes up in the facilitator's checklist. It is not the sceptical group's main worry.
• Stories from people whose schedules are very unusual.: Different schedules are raised by the first group, to defend personal stories.
• Stories that blame any failure on a lack of belief.: Blaming failure on weak belief is a warning from the speaker, later in the talk. It is not the sceptical group's point.

Correct Answer: About one in two.

Why this is correct: Twenty-four people were divided evenly, so the comparison group had twelve people. Six of those twelve is one in two.

Tips: When a group is divided, work out how many people are in each part.

Why the other options are wrong:

• About one in four.: Six out of all twenty-four people is one in four. But the question asks about the comparison group of twelve.
• About two in three.: Two in three is eight out of twelve. That was the list group, not the comparison group.
• About one in three.: One in three is eight out of twenty-four. That mixes the list group's number with the whole total.

Correct Answer: Critical of both, since each goes further than the results allow.

Why this is correct: Some wanted to drop the routine and others wanted to promote it. The speaker says both reactions outrun the evidence.

Tips: Separate the groups' reactions from the speaker's own judgement of them.

Why the other options are wrong:

• Critical of the doubters, since a gap of two people is meaningful.: The speaker calls the two-person gap interesting but far from proof. So the speaker does not side against the doubters.
• Critical of the promoters, since self-reports cannot be trusted.: The speaker mentions self-reports as a limit. But the speaker criticises the doubters too, not only the promoters.
• Pleased with both, since each group took the results seriously.: The speaker is not pleased with either reaction. Both go further than the evidence.

Correct Answer: It would make trying out ordinary habits seem too complicated.

Why this is correct: The first group worried that asking for research for every modest habit would make ordinary experimentation seem needlessly complicated.

Tips: Listen for the reason a group gives, not only its opinion.

Why the other options are wrong:

• Research rarely includes people with busy work schedules.: The group says people differ in schedules. They do not say research leaves busy people out.
• Formal studies take too long for most people to wait for.: The group never talks about how long studies take.
• A success story already shows how well a habit works for all.: The group says a habit's value is real for that person. They do not say it works for everyone.

Correct Answer: To show that good advice should let you see when it is not working.

Why this is correct: Such advice makes failure impossible to judge. The speaker contrasts it with useful guidance, which lets a person notice when it is not helping.

Tips: Think about which claim an example is used to support.

Why the other options are wrong:

• To show that good advice should come from someone who sounds less sure.: A confident voice is the sceptical group's worry. The belief example is about judging failure, not how sure a speaker sounds.
• To show that good advice should work for everyone who tries it.: The speaker never asks advice to work for everyone. The point is that you can tell when it fails.
• To show that good advice should suit each person's motivation.: Different motivation is the first group's point. The belief example is about judging failure.
