AND EVIDENCE – PRACTICE ASSESSMENT EXAM
350 UNIQUE MULTIPLE-CHOICE QUESTIONS
WITH DETAILED RATIONALES
SECTION 1: PROPOSITIONS AND NON-PROPOSITIONS (Questions
1–30)
1. Which of the following is a proposition?
A. Please close the door.
B. The Earth revolves around the Sun.
C. What time is it?
D. Wow, what a beautiful day!
Answer: B
Rationale: A proposition is a statement that can be true or false.

false. Commands (A), questions (C), and exclamations (D) are non-
propositions because they do not assert a claim that can be true or
false.

A. All humans are mortal.
B. Water freezes at 0 degrees Celsius.
C. Where did you put the keys?
D. The cat is on the mat.

claim about matters of fact.

3. A simple proposition is best described as:
A. A statement composed of multiple claims
B. A statement with no internal logical structure
C. A statement that always contains a conditional
D. A statement that requires evidence to evaluate
Answer: B
Rationale: Simple propositions have no internal logical structure—
their truth or falsity does not depend on whether a part of them is
,true or false. Examples include "The sky is blue" or "Harry Potter
wears glasses".

A. The sun is hot.
B. Birds can fly.

Answer: C
Rationale: Complex propositions have internal logical structure and
are composed of simple propositions. Their truth depends on
whether their parts are true or false. "The sky is blue, but it does not
look blue to me right now" combines two simple propositions with
the connective "but."
---
5. Which word is commonly used to identify independent
propositions in a complex proposition?
A. Therefore
B. Because
, C. But
D. Thus
Answer: C
Rationale: Words like AND, OR, EITHER, BUT, IF, and THEN are used
to connect independent propositions within complex propositions.
"But" joins two simple propositions into a complex one.

example of:
A. A simple proposition
B. A complex proposition
C. A non-proposition
D. A command

Rationale: This is a complex proposition because it contains an
internal logical structure (an "either/or" construction) and its truth
depends on the truth of its component parts.
