Question

read the passage. then, select the synonym of the word in bold. as the sun began to set, the island castaway was barely able to discern a ship on the horizon. did that mean that someone onboard the ship might be able to notice him, too? he jumped to his feet and frantically waved his arms, yelling, \over here! over here!\

Explanation:

Since the problem is about finding a synonym for "discern" and involves language and vocabulary, the subfield under Arts is Linguistics (or could also relate to Literature/Writing, but Linguistics focuses on language and words). However, as the problem is a synonym question, we can analyze the meaning of "discern" which means to perceive or notice. The context here is the castaway trying to see/notice a ship, and then wondering if someone on the ship can notice him (the word "notice" is used later, which is a synonym for "discern"). So the synonym would be a word like "notice", "perceive", "detect", etc. But since the problem is likely expecting a choice (though choices aren't provided here, assuming a typical synonym question), the process is:

The word "discern" in the passage means to perceive or notice something (here, the ship on the horizon). The context later uses "notice" (someone onboard noticing him), so a synonym for "discern" would be a word with a similar meaning like "notice", "perceive", "detect", etc.

Answer:

(Assuming common synonyms, e.g.,) notice (or other appropriate synonym like perceive, detect)
