Revise the passage below to remove the two shifts in verb mood. Your revised passage should use only imperative mood. Passage Driving is a big responsibility. If you drive, there are many things you must do to make sure your car is safe to drive. Be sure the lights and turn signals are working before you drive. Check the windshield wipers, in case you get caught in the rain. You should check the air pressure in your tires. Finally, get regular oil changes, and adjust your mirrors and seat before driving.

The lines that do not have an imperative mood are "Passage Driving is a big responsibility. If you drive, there are many things you must do to make sure your car is safe to drive." One way to modify revising this passage to make it in the imperative mood would be: "Passage Driving should be a big responsibility. If you drive, you must do it to make sure your car is safe to drive ..."

Explanation:

A passage presents an imperative mood when, when the speaker of the passage is issuing an order or a request to the executor. Thus, the verbs used in the passage must be combined to express a request, invitation, exhortation, order, command, advice or supplication.

In the case of the above passage, the first two sentences must be modified so that the whole passage takes on an imperative tone, showing what a person must do to achieve an efficient direction.
