How to ask a question according to “in order to catch a bus ” and "because I can catch a bus"?
"I get up early, because I need to catch the 7AM bus" - because answers the question "why?" The subclause gives a reason for the main clause.
"I get up early, in order to catch the 7AM bus" - The main clause is done so that the subclause can be satisfied - the subclause is somehow desired/required.
"in order to" can be converted to a "because", usually by adding a "want"/"will"/"need"/"must" etc.
The other way round is not always the case: "I did not go to school because I was sick" - here we cannot use "in order to" since there is no goal or purpose
A because B - B leads to A
A in order to B - B is the goal, and requires A
What do you want to achieve by getting up early? I get up early in order to catch the morning bus.
What is your reason for wanting to get up early? I get up early because if I don't, I will miss the morning bus.
Note that the question can really the same: why? The difference is how the answer is worded:
I think your intended answers are based on the fact that you must catch the morning bus to arrive to work on time. - I get up early in order to catch the morning bus. - I get up early because if I don't, I'll miss the morning buss. - I get up early so I can make it to work on time. - I get up early because I want to make it to work on time.
Following is a bunch of examples. I'm not sure if it's just me, but it seems that often the "because" answer is kind of worded in the opposite sense of the "in order to answer". It seems like "because" is the driving force or reason, and "in order to" is a goal state. Also, the "in order to" answer seems more cold/clinical/unemotional/to-the-point while the "because" has more emotion and a broader set of reasons. I don't know if this is just me though:
Why do you eat hamburgers? I eat hamburgers in order to gain weight.
Why are you eating hamburgers right now? Because their only $1 each.
Why are you eating hamburgers right now? Because [I want | I need] to save money, and their only $1 each.
Why do you eat food? I eat food in order to live. Note how well "in order to" answers an abstract question.
Why do you eat food? I eat food in order to satisfy my hunger. In order to has to carefully consider the goal state.
Why do you watch James Bond movies? I watch James Bond movies because I like James Bond.
Why do you watch movies? I watch movies because it's fun.
Why do you smoke? I smoke because I'm addicted to nicotine.
Because of (or on account of) what circumstance do you get up early?
is a question that (2) can answer, but (1) cannot. This takes advantage of the fact that in (2) you are indicating both a reason to get up early, and also a fact -- namely, that there is a bus to take (I 'can' catch a bus implies that there is a bus to take).
In (1) you might try to get up early to catch a bus, without expecting that one is very likely to be there. You might think there's only a fifty-fifty chance.
By contrast, I don't think that there is any question that (1) answers that (2) doesn't also answer. The reason is that (2) has 'extra information' but otherwise implicitly indicates a purpose, just like (1).
