(1) the minimum length of a password word is two letters, which can be the same or different.

(2) K cannot be the first letter of a word.

(3) If l appears, more than once

(4) M cannot make the last or second-to-last letter

(5) If K appears, N must appear.

(6) If O is the last letter, l must appear

Question 1: Which of the following letters can be placed behind o in Lo to form a three-letter password word?

A) k B) L C) m d) N

Question 2: If the letters K, L, and m can be obtained, what is the total number of two letter-length password words?

A) 1 B) 3 C) 6 d) 9

Question 3: Which of the following is the word password?
