Question

Which of the following sentences uses "their" correctly?
My best friend, Jamie, said she would never go their again. The sixth grade students studied the rules before their test. Sandrice loves her grandparents; their her favorite people. Their ready for the field trip to the Museum of Natural History.

Answer 1

The correct answer is B.) The sixth grade students studied the rules before their test.

Remember: "Their" is possessive, meaning the subject belongs to someone, "there" refers to a location, and "they're" is a combination of the words "they" and "are". 

Hope this helps!

Answer 2

'The sixth grade students studied the rules before their test' is the answer. This is because the word 'their' shows ownership and in this sentence the 6th graders own the test.
