4. Choose the comparison operator that makes a true statement: -1___0

None of these
<
>
=

<

<

To determine which comparison operator makes the statement "-1___0" true, we need to evaluate it.

In this case, we are comparing the numbers -1 and 0.

Since -1 is less than 0, the correct comparison operator that makes the statement true is "<" (less than).

Therefore, the correct answer is "<".
