Tom ate a hamburger. He () ate salad.

• A. Also
• B. But
• C. Then
• D. Yet

Answer: (A)

Showing addition between two actions after the same subject. When you want to say that Tom did another action in addition to eating a hamburger, you use also to add that second action. So “Tom ate a hamburger. He also ate salad.” conveys that salad was eaten in addition to the hamburger, without implying any order or contrast. The other options would change the meaning: but and yet introduce a contrast, and then suggests a sequence (afterward).
