Answer 2

The correct answer:

Don't leave temporary equipment plugging in when it's not in use.

About prepositions and their usage:

• Prepositions are words that relate the position of noun with the rest of the sentence. They tell about the posture of it.
• Some of the prepositions include: on, in, to, up, down, behind, near, over, beside, beneath, etc.,
• Sometimes two prepositions may be combined to form a new preposition and they may provide a new meaning as well. Some of which are: into, upto, upon, etc.,
• Here we should fill in the blanks with the right prepositions given as options.
• To fill in, we must read the sentence as a whole and gather its meaning.
• The answer we fill in, must make sense.
• So for the first blank, we have "don't" so it makes sense when we say we should not leave the equipment pugged in when it is not used.
• Therefore the option -'in, not in' is correct.
• Hence the answer is: Don't leave temporary equipment plugging in when it's not in use.
