____ my parents gave me the fish tank.
Correct Answer: EASY
Knowledge: Split sentence (stressed sentence)
Emphasis on adverbs (time, place, manner, reason, …):
It is/was + adverb + that + S + V + O
Here emphasizes a moment, so we must add the preposition “on” before “my birthday” to form an adverb of time.
Translated: On my birthday my parents gave me a fish tank.
