Consider a method named biggerThan that (1) takes two arguments - a list of ints named a and a single int named thresh; and then (2) returns a new list containing the elements from a that are > thresh; or None if there are no elements.

What should biggerThan return when called with a list a equal to [1, 2, 4, 6, 7, 8] and thresh set to 4? [1]

Provide example arguments a and thresh such that biggerThan should return a None. [1]

Write the method in correct, executable, Python. [3]
