• 1.

### If or unless? We're going to the concert _______ the tickets are sold out.

• A.

If

• B.

Unless

B. Unless
Explanation
The correct answer is "unless." This is because "unless" is used to express a condition that will result in a negative outcome if not met. In this case, the condition is "the tickets are sold out," and the negative outcome is not going to the concert. Therefore, the sentence means that we will only go to the concert if the tickets are not sold out.

### We will drive you to Santiago ____ your car isn't out of the garage by Friday.

Explanation
The correct answer is "if" because it indicates a condition or possibility. The sentence is saying that they will drive you to Santiago only if your car isn't out of the garage by Friday. It suggests that there is a chance that your car might be out of the garage by Friday, and in that case, they won't drive you.

### I will be unhappy _______ Chile wins the World Cup. (You support Chile!)

• A.

Unless

• B.

If

A. Unless
Explanation
The word "unless" indicates a condition that must be met in order for the statement to be true. In this case, the statement is "I will be unhappy," and the condition is "Chile wins the World Cup." The word "unless" connects these two parts, implying that the speaker will only be unhappy if Chile wins the World Cup. Since the speaker supports Chile, it can be inferred that they would be happy if Chile wins, making the statement false.

• A.

Unless

• B.

B. If
Explanation
The word "if" is the correct answer because it indicates a condition or circumstance that needs to be met for the speaker to be unhappy. In this case, the condition is Chile winning the World Cup. The speaker states that they will be unhappy only if Chile wins, implying that their happiness depends on Chile not winning.

### In case, unless, or if?I will pack my umbrella _____ it rains later.

• A.

If

• B.

Unless

• C.

In case

C. In case
Explanation
The correct answer is "In case". This is because the phrase "in case" is used to express a precaution or preparation for a possible future event. In this context, the speaker is saying that they will pack their umbrella as a precautionary measure in case it rains later. The word "unless" would imply a condition that must be met in order for the speaker to pack their umbrella, which is not the intended meaning. Similarly, "if" suggests a conditional statement, but the speaker is not stating a condition in this sentence. Therefore, "in case" is the appropriate choice.

C. In case
Explanation
"In case" is the correct answer because it is used to indicate that something is done as a precaution or preparation for a possible future event or situation. In this context, the person is putting money aside as a precautionary measure in case they have to give up their job.

Rate this question:

• 14.

### Rewrite the sentence to use if: I will take my umbrella unless it is sunny. You must keep the words: take – umbrella – sunny. Do not add words such as 'weather.'

If it isn't sunny, I will take my umbrella.
I will take my umbrella if it isn't sunny.
Explanation
The correct answer is a correct transformation of the original sentence using the word "if." It expresses the same meaning as the original sentence, stating that the person will take their umbrella only if it is not sunny.
