Multiple Choice. CHOOSE THE CORRECT ANSWER
1)Lucy... to Australia by plane next month​

The correct answer to the multiple-choice question is:

1) Lucy will travel to Australia by plane next month.

Explanation:

To answer this question, we need to determine the correct form of the verb to complete the sentence correctly. In this case, we are talking about a future action, so we need to use the future tense of the verb.

In English, to express the future tense, we often use the modal verb "will" followed by the base form of the main verb.

So, in the given sentence, "Lucy... to Australia by plane next month," the correct option is "will travel." This form indicates that Lucy plans or intends to travel to Australia in the future.

Other options that could be incorrect are:

a) traveled - This is in the past tense, indicating a completed action. It does not fit the context of the sentence, which is referring to a future event.
b) is traveling - This is in the present continuous tense, indicating an ongoing action in the present. It also does not fit the context of the sentence, which is referring to a future event.
c) travels - This is in the present simple tense, indicating a habitual or regular action. It does not fit the context of the sentence, which is referring to a future event.

To summarize, the correct answer is "Lucy will travel to Australia by plane next month." This option uses the future tense form "will travel," which accurately represents the intended future action.
