"1) We (to have) breakfast at 5:30 this morning."

The correct answer is "were having." In the sentence, we are talking about an action that happened in the past. When talking about past actions, we use the past continuous tense. The past continuous tense is formed using the past tense of the verb "to be" (in this case "were") followed by the present participle of the main verb ("having" in this case). So, the correct form is "were having."

2) "You (to take) photos with my new camera, weren't you?"

The correct answer is "were taking." In this sentence, we are again talking about a past action. We use the past continuous tense to describe an ongoing action in the past. The past continuous tense is formed using the past tense of the verb "to be" (in this case "were") followed by the present participle of the main verb ("taking" in this case). So, the correct form is "were taking."

3) "Robert (to lie) on the beach."

The correct answer is "was lying." In this sentence, we are talking about a single past action. To describe a single action in the past, we use the simple past tense. The simple past tense of the verb "to lie" is "lay," but when using the verb in continuous form, we use the present participle form, which is "lying." So, the correct form is "was lying."
