Given the task definition and input, reply with output. In this task, you will be shown an extract from a movie plot. You need to read the extract and create questions that can be answered from the extract. The questions should be well-formed and grammatically correct. The questions should be completely answerable from the given passage and should not require any external knowledge. Subjective questions are not allowed. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is factoid or not is to see if two different people with average reading/comprehension skills would come up with the same answer after reading the passage.

Mak Dong has just been released from the army and is on his way home, when he helps out a woman on the train. A couple of guys are hassling her, and he steps in gets his ass kicked and gets booted off the train. She calls him, because she collected his luggage and they agree to meet. It turns out she is a mobster's girlfriend and she gets him a job with the gang. Meanwhile his real family consists of 3 brothers, one is a wife beating detective, the second is severely handicapped and happy while the third sells eggs. He is still getting his ass kicked on a regular basis but the mob boss Bae Tse-Yong, takes him into the family and allows his to call him "Big Brother". Apparently this is a big thing among Korean mobsters. Now he's got two families and can't seem to handle either of them but one of them is going to be the death of him.
How many brothers does mak have?
