Answer 2

6 does not fit
7 smells
8 is smelling
9 are you looking
10 look
16 is
17 love
18  don't understand
19 have
20 tastes

На счёт глаголов исключений, в основном их используют в Present Simple.Но опять же тоже не всегда.Бывают случаи,когда их можно писать в Длительном времени.
К примеру  "This cake tastes awful."  здесь  taste  используют в SIMPLE 
Но  "I am tasting the soup" здесь в Continuous .
