Answer: 1. True
2. True
3. False
Step-by-step explanation:
1. 'Grandma's scissors' is plural so the verb 'are' fits perfectly.
2. 'last questions on the test' is plural so the verb 'were' fits perfectly.
3. 'Everyone' is plural so the verb should be 'needs' or 'needed', not 'need' since 'need' is for subjects that are singular.
