2c: Passive Voice (Future Tense-2012)

In this sentence, the verb "destroy" is in the future tense, indicated by the use of the modal verb "will" followed by the base form of the verb. The phrase "after two years" suggests that the destruction of the world will happen in the future, further supporting the use of the future tense. Therefore, the correct answer is "will be destroyed."

The correct answer is "will end." This is because the sentence is referring to a future event, the end of the world, which implies that it has not yet happened. Therefore, the future tense "will" is used to indicate that the end of the world will happen in 2012.

In 2012, it is expected that approximately 400,000 people will be chosen to board ships called "arks". This suggests that there is a selection process in place to determine who gets to board these ships. The phrase "will be chosen" indicates that the selection will happen in the future, further emphasizing the anticipation of this event in 2012.

The given answer correctly changes the sentence from active to passive voice. In the original sentence, "The ark will save Jackson and his family in 2012," the subject is "the ark" and the verb is "will save." In the passive voice, the subject becomes the receiver of the action, so "Jackson and his family" become the subject. The verb "will be saved" is used to indicate that the action is being done to the subject. The preposition "by" is used to show that the ark is the doer of the action. Thus, the correct passive voice sentence is "Jackson and his family will be saved by the ark in 2012."

The correct answer provides a correct transformation of the sentence from active to passive voice. It accurately changes the subject "The American geologist" to the object "The US president" and rephrases the action "will tell" to "will be told". The rest of the sentence remains unchanged, maintaining the correct tense and meaning.
