The little priest was not an interesting man to look at, having stubby brown hair and a round and stolid face which did not give away anything.

The word STOLID in the above sentence means:

Option 1 -> Frowning is a specific facial expression showing disapproval or concentration, not the meaning of stolid.

Option 2 -> Darkish refers to a color or shade, which doesn't relate to facial expression or demeanor.

Option 3 -> Emotionless means showing no feelings or expressions, which aligns with "did not give away anything."

Option 4 -> Hateful means showing intense dislike or malice, which is a specific negative emotion rather than absence of expression.

Hence, Option 3: Emotionless -> "Stolid" describes someone who shows little or no emotion and remains calm and unemotional. The context clue "which did not give away anything" confirms that the priest's face revealed no emotions or feelings -> correct
