4. proficient = He is proficient at both Math and Arts.

Explanation: Anyone is singular, thus, use a singular verb --> sees. Be careful of word spelling (douring --> during). Capitalize Proper nouns such as school subjects (Math, Arts). art and Arts are different to each other. Arts is a school subject and art is the making of artistic things such as painting and drawing.
