Q1. The book was left on the table when I left the classroom.
In this sentence, we need to determine the correct form of the verb "to be" to fill in the blank. To do this, we should first identify the tense being used. In this case, the action of leaving the classroom happened in the past, so we should use the past form of the verb "to be," which is "was." Therefore, the correct answer is "was."
Q2. This building was built 20 years ago.
Again, let's identify the tense being used in this sentence. The action of building the building happened in the past, so we should use the past form of the verb "to be," which is "was." Additionally, the verb "to build" is in the past participle form, which is used when talking about actions that happened before a specific point in the past. Therefore, the correct answer is "was built."
Q3. The cake was made by my mother not long ago. Let's try!
In this sentence, we once again need to determine the correct form of the verb "to be" to fill in the blank. The action of making the cake happened in the past, so we should use the past form of the verb "to be," which is "was." Therefore, the correct answer is "was."
Q4. Tom was bitten by a dog just an hour ago, so he is in the hospital now.
For this sentence, we need to determine the correct form of the verb "to be" to fill in the blank. The action of Tom being bitten by a dog happened in the past, so we should use the past form of the verb "to be," which is "was." Therefore, the correct answer is "was."
