Question

Which sentence has the correct subject-verb agreement? Saturn, which is the sixth planet from the sun, rotate every 10 hours and 14 minutes. Saturn, along with Jupiter and Uranus, has rings that encircle the planet. Scientists who study the universe has several theories about the rings around planets.

Answer 1

Saturn, along with Jupiter and Uranus, has rings that encircle the planet.

Answer 2

2. Saturn, along with Jupiter and Uranus, has rings that encircle the planet.

Step-by-step explanation:

In a sentence with correct subject-verb agreement, the subject and the verb match in person (1rst, second or third person) and number (singular or plural). Therefore, sentence number 2 is the correct sentence because the subject matches in person and in number with the verb: The subject "Saturn" is in third-person singulars and so does "has".

In the other sentences, "Saturn" does not match the verb "rotate" (It should be "rotates" instead) and " Scientists" does not match its verb "has" (It should be "have" instead).
