ANSWER KEY & EXPLANATIONS
1 c
Explanation: (c) is correct. “So” connects the problem (it is hot) with the result/solution (open the window). (a) is a common mistake (using “because” introduces a reason, not a result). (b) is a meaning error (“but” is for contrast).
2 a
Explanation: (a) is correct. “I” takes the base verb “need”. (b) is a structural error (adding “-s” to the verb for “I”). (c) is a structural error (mixing “am” with the base verb “need”).
3 b
Explanation: (b) is correct. “So” introduces the action taken because of the rain. (a) is a common mistake (“because” would mean the reason we stay home is the rain, but the clause order is reversed: We are staying home because it is raining). (c) is a meaning error.

GRAMMAR POINTS TO REMEMBER
1 Using “So” for Solutions: When you experience a problem and want to state the action you will take to fix it, use the conjunction “so”.
- Formula: [Problem/Cause] + so + [Solution/Result]
- Example: It is hot, so I will open the window.
2 “So” vs. “Because”: These two words are opposites in sentence structure. Many learners confuse them.
- Because introduces the reason (I will open the window because it is hot).
- So introduces the result (It is hot, so I will open the window).
3 Grammar after “So”: After “so”, you must use a complete sentence structure or a valid command.
- Subject + Verb: …so I need some water.
- Subject + Modal Verb: …so I can’t buy it.
- Let’s + Base Verb: …so let’s go home.
- Imperative: …so please turn it down.
