To determine the missing word that describes Tom's brother, let's analyze the given sentence. The sentence states that Tom is "refined," indicating that he possesses good manners, sophistication, or cultivated taste. We are tasked with finding a word to describe Tom's brother, which is the opposite of refined.

Option (a) "arrogant" means having an exaggerated sense of one's own importance and is not the direct opposite of refined.

Option (b) "crude" means lacking refinement or tact and aligns with the intended meaning of the sentence. It is the word that describes Tom's brother as the opposite of refined, making it the most suitable answer.

Option (c) "unskillful" refers to a lack of skill and is not directly opposite in meaning to refined.

Option (d) "foolish" means lacking common sense or good judgment and does not directly convey the opposite of refined.

Therefore, the correct answer is (b) crude.
