Question

1. which sentence demonstrates correct subject - verb agreement? the flowers blooms beautifully in the spring. sam works with his dad. the stars shines at night. some candidates promises to build a new playground.

Explanation:

Subject - verb agreement means a singular subject takes a singular verb and a plural subject takes a plural verb. "The flowers" (plural) should have "bloom", not "blooms"; "The stars" (plural) should have "shine", not "shines"; "Some candidates" (plural) should have "promise", not "promises". "Sam" (singular) with "works" (singular verb) is correct.

Answer:

Sam works with his dad
