Answer:
Prepositions.
Explanation:
Prepositions are parts of speech that tell us the time, location, direction, place, or even relationships in a sentence. They are used to introduce an object and are placed before nouns or pronouns.
Examples of prepositions are "at, in, under, by, to, behind, since" etc. These prepositions can be used to signify the time, location, or space in a sentence.
Examples of these prepositions in a sentence are-
<em>Time- I have been studying </em><em>since </em><em>morning.
</em>
<em>Space- My umbrella was </em><em>under </em><em>the bed.
</em>
<em>Location- I was taking a class </em><em>in </em><em>the hall.</em>
I think that your assignment is asking you to film something. Your teacher is leaving it up you to decide how to make that video. What it's saying is you can use one of the example ideas or come up with your own.
