The sentences in the excerpt require revision or correction because they:
B. Contain generalizations and contradictions.
We generalize something when we apply the little knowledge we know about one case or instance to all cases or instances. For example, if someone says that all people who work for a certain company are rude, they would be making a generalization.
A contradiction happens when we say something opposite to something else we said before. You would contradict yourself if you said all music festivals are bad but that the one happening next week is good.
Those are the problems we have in the excerpt. The writer makes generalizations about the distance between our planet and the stars and about our technological capacity to reach them.
The writer also contradicts himself when he says we cannot go to the stars and then says we would take long to get to them. Taking long means that we would, eventually, go to the stars.
