Direction (1-10): Choose the correct conjunction in each sentence.
1. ------ my friend ------ I are taking the geography class.
Answer: Both, and
Explanation: Here we have two subjects so, the conjunction 'both' should be used in the first blank. Now for the second blank, one can be confused between the usage of 'and' and 'or' but a careful observation of the sentence would help you to observe that 'and' is the most appropriate answer. Since, both 'my friend' and 'I' are the doors, besides this, the usage of verb 'are' also suggests that 'and' is the correct answer since, if am should have been the answer, 'am' should have been used in place of 'are'. Refer to the chapter 'Subject-Verb Agreement' for a detailed explanation.
2. Do you want to go swimming ------- golfing?
Answer: or
Explanation: Here, a choice has to be made between 'swimming' and 'golfing'. Hence, 'or' is the correct answer.
3. I studied grammar for a long time, -------- I still make mistakes.
Answer: but (yet)
Explanation: Here, the latter part of the sentence is in contrast with the former part of the same. Hence, the conjunction 'but (or yet)' should be used.
4. ------- wood -------- bricks can be used as homebuilding materials.
Answer: Either, or
Explanation: Here we have two choices (i.e. 'wood' and 'bricks') out which one has to be chosen. In such cases, we use 'either' before the first choice and 'or' before the second.
5. I wasn't feeling well this morning,-------- I had to go to work.
Answer: yet (but)
Explanation: Here, the latter part of the sentence is in contrast with the former part of the same. Hence, the conjunction 'but (or yet)' should be used.
6. Could you email me --------- you receive the offer?
Answer: when
Explanation: The latter part of the given sentence indicates a particular 'point of time' (i.e. time of receiving the offer). Hence the conjunction of time 'when' should be used here.
7. I want to buy it -------- is expensive or not.
Answer: whether
Explanation: Here, 'whether' should be used. Note that, 'or' can be used with both 'either' and 'whether'. However, the sense in which it is used is not the same. 'either....or' is used to denote a choice between two (or more) alternatives, whereas, 'whether....or' is used to introduce two or more possibilities, and generally means 'it is not important if'.
For Example: Whether or not you like it, I'm going out tonight.
8. Don't do that --------- I allow it.
Answer: unless
Explanation: Here, the latter part of the sentence puts a condition on the action being done in the former part of the same. Hence, the conjunction 'unless' should be used.
9. --------- you are confident with it, you should go for it.
Answer: If
Explanation: Here, the former part of the sentence puts a condition that the latter part is possible or will happen only if it becomes true. Hence, conjunction 'if' is should be used.
10. I didn't enroll this semester ---------- I could go backpacking in Europe.
Answer: so that
Explanation: Here, the second part shows the reason or purpose of the action done in the first part, hence, the conjunction 'so that' should be used.
Note: "So that" is used as a subordinate clause to show purpose or to give an explanation. It is used to show an action producing an intended result or a cause producing an effect.

Direction (1-10): Choose the correct conjunction in each sentence.
1. My neighbor's cat has been missing --------- last Friday.
Answer: since
Explanation: Here a particular point of time (last Friday) is being described, hence, 'since' should be used.
2. ---------- I own a house, I am required to pay property taxes.
Answer: Because
Explanation: Here, the first part gives the reason for the occurring of the second part, hence, 'because' should be used.
3. Hurry up; ----------, you will be late for the train.
Answer: otherwise
Explanation: Here, a suggestion is made that the listener can get late for the train if he doesn't hurry up, hence, 'otherwise' should be used here. 'Otherwise' is used after an order or suggestion to show what the result will be if you do not follow that order or suggestion.
4. I studied hard for the exam; ----------, I failed.
Answer: however
Explanation: Here, despite a high degree of hard work 'I' failed, In such cases, when despite whatever amount or degree one doesn't get the desired results, 'however' is used. Note: Yet can also we the answer.
