A person reading a new book for pleasure is like a tourist traveling to a new place.
Conclusion (thus)
It is better to read fewer books and spend more time on each than to read as many books as you can.
Evidence
The author draws an analogy between reading new books and traveling to new places, suggesting that both activities aim to enlarge understanding.
Evaluate
This is a "Strengthen" question focusing on an analogy between reading books and traveling. To bolster this analogy, seek additional evidence that supports the strategy of focusing on fewer books or places for deeper comprehension. We are particularly interested in highlighting cases where spending more time on fewer subjects leads to a better understanding.
Goal
Look for an answer that supports the analogy by showing that focusing deeply on a few subjects (in reading or traveling) is more effective for understanding, compared to quickly skimming through many.
