Answer #1

Answer: E. [606, 608, 610, 612, 629] [608, 610]

Explanation:

In the first for loop 606 to 612 all even numbers are added to list s; i.e., 606 608 610 612

in the next statement subset of s from 608 to 610 are added to list subs ;

in the next statement 629 is added to list s.

Therefore the output should be: [606, 608, 610, 612, 629] [608, 610]
