Answer 1

The sentences that incorrectly leave out a necessary comma in a series are:

B. The store sells jackets hats gloves and scarves for winter.
D. The team practiced basketball soccer and volleyball all week.

Both sentences are missing commas before the conjunctions in the series, which should make them read:

B. The store sells jackets, hats, gloves, and scarves for winter.
D. The team practiced basketball, soccer, and volleyball all week.
