Explanation:

Let’s cut through the noise and get right to it:

- Ex post measures (Option 1) — ?? These show the *actual* values that happened, like what people really spent, invested, or produced. This is the data after everything’s said and done.

- Ex ante measures (Option 2) — This is what people *intend* or *plan* to do—so before the fact, not the actual numbers that play out.

- Ex pre measures (Option 3) — This isn’t a standard term you’ll see in economics. It’s not commonly used or accepted. Ignore it.

- None of the above (Option 4) — Not needed here because one of the listed options is definitely correct.

Correct answer: ex post measures (Option 1).

Actual values are always “ex post”—what really happened—not what anyone expected or planned.
