Answer :

Let's go through each sentence and answer the questions:

  1. "Would you mind if we ______ you by your first name?" - "Not at all. Please call me Tom."

    The correct option is A. called.

    Explanation: This sentence is asking for permission in a polite way. The phrase 'Would you mind if we...' is usually followed by the past tense to express a polite request or hypothetical situation. Thus, "called" fits correctly here.

  2. It's very crowded here. I wish there ______ so many people.

    The correct option is B. weren't.

    Explanation: "I wish" is commonly used to express a desire for something that is not true at present. In this case, using "weren't" (the past subjunctive form) is appropriate to express this wish about the present situation.

  3. We can help ______ the environment by using green and sustainable energy sources.

    The correct option is C. save.

    Explanation: To "save the environment" is a common expression that means to protect or conserve the natural world. By using "save," the sentence conveys the idea of taking actions that benefit the environment.

  4. Seattle is one of the most ______ cities in the US.

    The correct option is C. eco-friendly.

    Explanation: "Eco-friendly" is an adjective that describes something that is not harmful to the environment. The sentence suggests that Seattle is recognized for its environmentally friendly practices.

  5. According to the weather forecast, it will be fine at the weekend. If the weather ______ fine, we ______ on camping at the weekend.

    The correct option is A. is - will go.

    Explanation: This is a first conditional sentence, used for real or possible situations in the future. The structure is "if + present simple, will + base verb." Here, "is" and "will go" fit the structure, indicating that the camping trip depends on the actual weather conditions.
