Which approach is least effective when encountering a difficult CARS passage?

The least effective approach when encountering a difficult CARS passage is to skim the passage quickly without engaging with its content. This method often results in a superficial understanding of the text, failing to capture important details, nuances, and the overall argument being presented. Effective comprehension in the CARS section typically requires a deeper analysis of the passage, which allows for the identification of key themes, rhetorical strategies, and the author's intent.

In particular, engaging with the content critically supports better retention and understanding of the material. Identifying key themes allows a reader to grasp the main ideas and arguments more effectively, which is crucial for answering questions accurately. Taking notes can also reinforce retention and comprehension by encouraging active involvement with the text. Consequently, skimming misses opportunities for meaningful engagement, making it an ineffective strategy in tackling challenging passages.
