Because early computers used vacuum tubes for memory, they were bulky and slow.

The two verbs are USED and WERE.

Which form do you think these verbs are in? We'll be glad to check your answers.

Past Form, not sure if were is past participle?

You're right. Both are in the past tense. Past participles need a helping verb -- and there are no helping verbs in this sentence.

The verb(s) in the first sentence are "used" and "were."

- "used" is the simple past form (past) of the verb "use."
- "were" is the simple past form (past) of the verb "be."

To identify the verbs and their forms, you can follow these steps:
1. Identify the words that convey the action or state of being.
2. Determine the tense of the verb. In this case, both "used" and "were" are in the past tense.
3. Once you have identified the verb and its tense, you can categorize the verb as the base form (b), present participle with auxiliary verb (pp), simple past form (past), or past participle with auxiliary verb (past p).
