Which of the following states that if a writing, or term in question, appears to be plain and unambiguous on its face, its meaning must be determined from the four corners of the instrument without resort to outside evidence, with the words being given their ordinary meaning?
A. The Interpretation Rule
B. The Simple Rule
C. The Understandable Rule
D. The Plain Meaning Rule
E. The Comprehensive Rule

D. The Plain Meaning Rule

Explanation:

Plain meaning rule is a type of statutory construction in which statues are to be interpreted using the ordinary meaning of the language of the statue. This applies when there is no ambiguity in it as seen in this question.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
