Answer 1

Answer:

Answer 2

14. She  Option(B) was preparing food when the guests arrived yesterday.

• The statement means when the guests arrived on the previous day, she was still cooking.
• We have used "was preparing" as the event has already occurred but it was in a continuous motion.
• We cannot use 'is preparing' because it is mentioned the event that happened yesterday, i.e past tense.

• We cannot use 'preparing' because it will result in a grammatical error, and the event that happened yesterday, i.e past tense.

• We cannot use 'has been preparing' because it will result in a grammatical error.
