Answer:
Es posible que ellos reciban más dinero.
Explanation:
The sentence "Es posible que ellos reciban más dinero" is well written and It is correct.
Sentences like the following would be wrong in Spanish:
1) * Ellos que reciban más dinero es posible.
2) * Dinero más posible es reciban ellos que.
In Spanish, as you can see, we require a word order as in English. That is, Subject, verb, object. In sentence 1 we have the subject "ellos" that is not followed by a verb so It is ungrammatical. Then, the same happens in sentence 2.
