i dont get this question sololearn asks me, i would like to know why

Question

if not True:

print("1")

elif not (1 + 1 == 3):

print("2")

else:

print("3")

Answer 1

If not True = False
Elif not (1+1==3) = elif not (False) = True

That Prints 2

Answer 2

As Christian said:
The first check (if not True) results as false, so that option doesn't get used.

The second check (elif not(1+1=3)) results as false(false) so becomes true. Runs that option to print 2.

Third option doesn't get checked because second option was used.
