A.I. Explanation:

Correct answer: worthy of

Explanation: The phrase 'worthy of' fits grammatically as it indicates that the information should be considered valuable enough to be written down. This aligns with the context of assessing the importance of information, making it the most suitable choice.

Meaning: 'Worthy of' means deserving of attention or consideration, implying that the information has value that justifies being noted.

Wrong options:

• revered for: This phrase suggests being highly respected, which does not fit the context of evaluating information for note-taking.
• deserved by: This implies entitlement, which does not align with the assessment of information's value for writing down.
• mandatory for: This indicates a requirement, which does not match the subjective evaluation of what should be noted.

Correct answer: them

Explanation: The pronoun 'them' correctly refers back to 'notes,' maintaining pronoun-antecedent agreement in number and gender. It fits contextually as it indicates the notes taken by the individual.

Meaning: 'Them' is a pronoun used to refer to multiple items or people, in this case, the notes that have been taken.

Wrong options:

• those: While 'those' could refer to the notes, it is less direct and does not fit as smoothly in the sentence structure compared to 'them.'
• any: This word implies a non-specific quantity, which does not accurately reflect the specific notes taken by the individual.
• it: This pronoun is singular and does not agree with the plural noun 'notes,' making it grammatically incorrect.

Correct answer: reap the rewards

Explanation: The phrase 'reap the rewards' fits contextually as it suggests that students will benefit from their efforts in organizing notes. It also aligns with the overall positive tone of the passage regarding the benefits of note-taking.

Meaning: 'Reap the rewards' means to receive benefits or positive outcomes as a result of one's efforts or actions.

Wrong options:

• rest on their laurels: This phrase implies complacency after past successes, which contradicts the proactive nature of taking notes and preparing for exams.
• rest assured: This phrase provides reassurance but does not convey the idea of gaining benefits from effort, making it contextually irrelevant.
• return the favour: This phrase suggests reciprocation, which does not relate to the context of benefiting from diligent note-taking.

Correct answer: warrant

Explanation: The verb 'warrant' fits grammatically as it indicates that the benefits of note-taking justify its high ranking among study skills. It aligns well with the context of discussing the importance of note-taking.

Meaning: 'Warrant' means to justify or necessitate something, in this case, the high ranking of note-taking skills.

Wrong options:

• condone: This means to accept or allow something, which does not fit the context of justifying the importance of note-taking.
• advocate: This implies support or recommendation, which does not directly convey the idea of justification needed in this context.
• rationalise: This means to explain or justify, but it does not fit as well as 'warrant' in the context of ranking study skills.
