Question

should there be a comma before the highlighted word? enrique rivera is an expert at both juggling, and riding a unicycle. keep the comma

Explanation:

In this sentence, "juggling" and "riding a unicycle" are two parallel elements joined by "and". When there are only two parallel elements joined by a coordinating conjunction like "and", a comma is not typically used before the conjunction.

Answer:

No, there should not be a comma before "and".
