Sure, I'll be happy to help you with your question as if I were a school teacher.

The sentences in the exercise require the use of the words "was," "were," "wasn't," or "weren't." These words are forms of the verb "to be" in the past tense. Let's go through each sentence step by step and figure out which form of the verb to use.

1. My friends and I ________ playing soccer yesterday.
To determine the correct form of the verb, we need to look at the subject of the sentence, which is "My friends and I." Since this subject is plural (referring to more than one person), we should use the plural form of the verb "to be," which is "were." Therefore, the correct answer is "were."

2. The cat ________ hungry this morning.
In this sentence, the subject is "The cat," which is singular (referring to only one cat). Since the subject is singular, we should use the singular form of the verb "to be," which is "was." Therefore, the correct answer is "was."

3. They ________ at the party last night.
The subject in this sentence is "They," which is plural. Similar to the first sentence, we should use the plural form of the verb "to be," which is "were." Therefore, the correct answer is "were."

4. It ________ raining when we went outside.
The subject here is "It," which is singular. So, we should use the singular form of the verb "to be," which is "was." Therefore, the correct answer is "was."

5. He ________ at home yesterday.
The subject in this sentence is "He," which is singular. Again, we should use the singular form of the verb "to be," which is "was." Therefore, the correct answer is "was."

I hope this explanation helped you! Remember to use "were" for plural subjects and "was" for singular subjects in the past tense. If you have any more questions, feel free to ask!
