Conditionals: If, In Case And Unless.

The correct answer is "unless". This conjunction is used to express the condition that the car breaking down is the only circumstance in which we will not drive to Santiago. In other words, if the car doesn't break down, we will drive to Santiago.

The correct answer is "if". This conjunction is used to introduce a condition or supposition. In the given sentence, it indicates that the speaker will be late for the test if there is a lot of traffic and they leave at the normal time.

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.

The correct answer is "if" because it indicates a conditional statement. It suggests that the speaker will go to the concert only if the tickets are not sold out.

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.

The correct answer is "in case" because it implies that the person will get up early on test day as a precautionary measure, anticipating the possibility of encountering heavy traffic. It suggests that the person wants to be prepared and ensure they arrive on time for the test, even if there is a lot of traffic.

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.

The correct answer is "Unless". This conjunction is used to introduce a condition that must be met for a particular result to occur. In this case, it suggests that if the speaker does not leave very early, they will be late.

The correct answer is "If". This is because the sentence is expressing a condition or possibility. It is saying that if the person leaves early, they won't be late. "Unless" and "in case" are not appropriate in this context as they do not convey the same meaning of a conditional statement.

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.

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.

"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.

The correct answer is "Unless" because it indicates a condition that must be met for the person to take their umbrella. It implies that the person will only take their umbrella if it is not sunny.

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.
