The window was open and a bird _____ into the room. (fly)

• A. flew
• B. is flying
  
• C. will fly
  
• D. has flown
  

Answer 1

Answer: (A)

The simple past (also called past simple, past indefinite) is a verb tense which is used to show that a completed action took place at a specific time in the past. The simple past is also frequently used to talk about past habits and generalizations. The simple past is formed using the verb + ed. Questions are made with did and negative forms are made with did not.

Since, we are talking about an action which has happened in the past, we will be using simple past tense. The verb here is "fly" thus the simple past tense is flew

Option A is correct
