The conjunctions 由于 and 因为 indicate "reason" and are usually used in the first clause of a complex sentence.
1) There is often 才 or 所以 in the main clause to echo with it; 由于 can also have 因此 or 因而 to echo with it.

2) In the examples ① and ② above, either 由于 or 因为 can be used. In the examples ③ and ④, however, 因为 cannot be used in the first clause as it is 因此 or 因而 in the second clause.
