Correct answer: enlisted
Explanation: The word 'enlisted' fits grammatically as it indicates that Wendy Hall and her team actively recruited or signed up 42 volunteers for their study. This aligns with the context of conducting research, where volunteers are often enlisted to participate in studies.
Meaning: 'Enlisted' means to enroll or recruit someone for a specific purpose, in this case, to help with the investigation of the link between sleep and diet.
Wrong options:
- collided: 'Collided' means to crash or come into conflict, which does not fit the context of recruiting volunteers for a study.
- summarized: 'Summarized' means to give a brief statement of the main points, which does not apply to the action of recruiting participants.
- indicted: 'Indicted' means to formally accuse someone of a crime, which is completely unrelated to the context of gathering volunteers for research.
Correct answer: routine
Explanation: The word 'routine' is appropriate as it refers to a regular pattern of behavior, which is essential for establishing good sleep habits. This fits contextually with the advice given to participants about improving their sleep.
Meaning: 'Routine' means a sequence of actions regularly followed, in this case, a set of practices to help improve sleep quality.

Correct answer: extended
Explanation: The word 'extended' fits grammatically and contextually as it describes sleep patterns that have increased in duration. This aligns with the findings of the study regarding the effects of sleep advice on participants' sleep duration.
Meaning: 'Extended' means to increase in length or duration, in this case, referring to longer sleep patterns observed in participants who received advice.
Wrong options:
- exercised: 'Exercised' means to engage in physical activity, which does not relate to the context of sleep patterns.
