Explanation:
The demonstrative pronouns in English are four:
- this (singular)
- that (singular)
- these (plural)
- those (plural)
When referring to objects that can be seen by both the speaker and the listener:
- "this" and "these" refer to objects near the one who speaks;
- "that" and "those" refer to objects far from the speaker or even far from both, speaker and listener.
In the sentences we completed above, we cannot know what is near and what is far since there are no pictures. However, you will notice that some sentences use the present tense while others use the past tense. This is our clue. The ones using the past will most likely be completed with "that" or "those", because the verb is referring to actions that are "far". Likewise, sentences in the present will most likely be completed with "this" and "these" for referring to an action that is closer / nearer.
