Explanation / Answer
In general, testable statements are those of the form: "If (or when) X happens, then Y happens". Whereas non testable statements are states as facts: "X is greater than Y" "4 X were found in Y" Thus, for example, (1) is testable: WHEN a plant is placed on a window sill, it GROWS faster. But, (2) is non-testable: The teller with brown hair and brown eyes IS taller than the others. Following this logic: (1), (4), and (9) are testable, and (2), (3), (5), (6), (7), and (8) are non-testable.
