Explanation:

Translations

Es cierto que hay mucha agua. -> It is true that there is a lot of water.

No es verdad que estemos tristes. -> It is not true that we are sad.

Estoy contento que haya dinero en el banco. -> I am happy that there is money in the bank.

Mi madre quiere que yo haga mi cama. -> My mother wants me to make my bed.

Let's number the sentences.

In #1, there is nor emotion, influence, or doubt. It is a stated fact.

In #2, there is a doubt ("It is not true...")

In #3, there is an emotion, happiness ("I am happy that...")

In #4, there is influence, as "my mother wants;" she is influencing the narrator to make their bed.

Thus, the first sentence does not contain influence, an emotion, or doubt.
