What is the meaning of the word 'abstain' as used in the last paragraph?
- A. Dishonor
- B. Go without
- C. Connect to
- D. Liberate
Correct Answer: B
Rationale: In the context of the passage, 'abstain' means to refrain from or go without. The passage discusses the challenges of treating individuals with both eating disorders and substance abuse issues. It mentions that while treatment for addiction involves abstinence, it is not possible to completely abstain from food. This highlights the meaning of 'abstain' as 'go without' in this context. The other choices are incorrect: 'Dishonor' does not relate to abstain, 'Connect to' is not synonymous with abstain, and 'Liberate' does not align with the context of the passage.
What is the meaning of the word 'admonition' as used in the last paragraph?
- A. Permission
- B. Prescription
- C. Caution
- D. Verdict
Correct Answer: C
Rationale: In this context, 'admonition' means a caution or warning, not permission, prescription, or verdict. The excerpt mentions that along with advising the elderly to move slowly and carefully, the CDC also recommends gentle exercise or physical therapy to strengthen muscles and improve balance. This advice aims to reduce the risk of falls and boost the self-esteem of older adults. Therefore, 'admonition' here refers to a precautionary counsel rather than granting permission, prescribing a treatment, or giving a verdict.

The word 'alterations' best captures the idea that significant changes are occurring in the brain. 'Stints' (choice B) refer to short periods of time or work, which is not the meaning intended here. 'Removals' (choice C) and 'transfers' (choice D) do not fit the context of the sentence and are not related to the changes happening in the brain as described in the extract.
