Which sentence contains grammar and usage errors and needs revision?

sentence 1
sentence 2
sentence 3
sentence 4

Answer 1

1 and 2 are wrong. In 1 it must be "to send a pilot to a mission to Mars" and 2 must be with one . So the whole answer will be: "In the global news recently, there has been a push to send a pilot to a mission to Mars, but scientific experts argue that sending people is unnecessary."
