Mark the reason or result

Instructions:

For each sentence, determine whether the conjunction 'so' or 'because' indicates the reason or the result, and fill in the blank accordingly. The provided sentences are examples, and the task is to understand the grammatical function of these conjunctions in context.

Examples:

1. I'm going to be in our lesson in time, so I need to go out right now. (Here, 'so' indicates the result: being in time is the condition, and needing to go out is the consequence/result.)
2. I need to go out right now because I'm going to be in our lesson in time. (Here, 'because' indicates the reason: needing to go out is the action, and being in time for the lesson is the reason for it.)
3. He is going to buy a ticket for this match because he really likes football. (Reason: liking football is the cause for buying a ticket.)
4. He really likes football, so he is going to buy a ticket for this match. (Result: liking football is the reason, and buying a ticket is the consequence.)

Note: This task requires understanding the cause-and-effect relationship in sentences. 'Because' typically introduces the cause (reason), while 'so' typically introduces the effect (result).
