Achievement Test Questions
1. Read the following sentence: "The scientist meticulously recorded every observation, ensuring no
detail was overlooked." What does meticulously mean?
A. Carelessly
B. With great attention to detail
, C. Quickly
D. Loudly
Correct Answer: B. With great attention to detail
Rationale: The context ("ensuring no detail was overlooked") indicates carefulness. "Meticulously"
means precisely and thoroughly. "Carelessly" (A) is the opposite. "Quickly" (C) and "loudly" (D) are
unrelated.
2. Solve for x: 3(x + 4) = 21
A. 3
B. 5
C. 7
D. 9
Correct Answer: A. 3
Rationale: Divide both sides by 3: x + 4 = 7. Subtract 4: x = 3. Option B results from forgetting to divide
first. C and D are arithmetic errors.
3. Which sentence is grammatically correct?
A. Each of the students have completed their project.
B. Neither the teacher nor the students was prepared.
C. The team are celebrating their victory.
D. Everyone has submitted his or her assignment.
,Correct Answer: D. Everyone has submitted his or her assignment.
Rationale: "Everyone" is singular and requires a singular verb ("has") and pronoun ("his or her"). A
uses plural "have" with singular "each." B should be "were" (plural verb with closer plural subject
"students"). C treats collective noun "team" as plural; in American English, it’s usually singular.
4. In an experiment, plants given more sunlight grew taller than those in shade. What is the
independent variable?
A. Plant height
B. Amount of sunlight
C. Type of soil
D. Water amount
Correct Answer: B. Amount of sunlight
Rationale: The independent variable is what the researcher changes (sunlight). Plant height (A) is the
dependent variable. Soil (C) and water (D) are controlled variables.
5. The U.S. Constitution establishes a system of checks and balances to:
A. Ensure one branch becomes more powerful
B. Prevent any one branch from dominating the others
C. Allow states to override federal laws
D. Give the president ultimate authority
Correct Answer: B. Prevent any one branch from dominating the others
Rationale: Checks and balances distribute power among legislative, executive, and judicial branches
to prevent tyranny. A, C, and D describe imbalances, not the system’s purpose.
, 6. If a car travels 240 miles in 4 hours, what is its average speed?
A. 40 mph
B. 50 mph
C. 60 mph
D. 70 mph
Correct Answer: C. 60 mph
Rationale: Speed = Distance ÷ Time = 240 ÷ 4 = 60 mph. A and B are too low; D is too high.
7. Which word is a synonym for ambiguous?
A. Clear
B. Confusing
C. Obvious
D. Precise
Correct Answer: B. Confusing
Rationale: "Ambiguous" means open to multiple interpretations or unclear. "Confusing" is a close
synonym. A, C, and D are antonyms.

A. 17 cm²
B. 34 cm²
