Question 1 · English and Language Usage
Which revision most clearly improves the development of the paragraph? Original sentence: “The internet has changed many things, including the way people buy groceries.”
- A.The internet affects everyone.
- B.The internet is popular around the world.
- C.Many people like using the internet.
- D.Online grocery shopping has transformed consumer behavior by offering convenience and time-saving options.
Show answer and explanation
Answer: D. Online grocery shopping has transformed consumer behavior by offering convenience and time-saving options.
The revision about online grocery shopping develops the idea precisely by explaining how the internet has changed grocery shopping (convenience and time savings). The other choices are vague generalizations that add no development.

Which revision corrects the run-on sentence? Original: “He studied all night he was tired.”
- A.He studied all night. He was tired.
- B.He studied all night, he was tired.
- C.He studied all night and he tired.
- D.He studied all night he is tired.
Show answer and explanation
Answer: A. He studied all night. He was tired.
“He studied all night. He was tired” separates two independent clauses correctly using a period.
Question 3 · Geometry
The area of a triangle is 30 in² and the base is 5 in. What is the height?
- A.12 in
- B.6 in
- C.8 in
- D.10 in
Show answer and explanation
Answer: A. 12 in
A = (1/2) × b × h, so 30 = (1/2) × 5 × h = 2.5h, and h = 30 ÷ 2.5 = 12 in.
Question 4 · Science (Optional)
Which organelle produces most of the ATP (usable energy) in a eukaryotic cell?
- A.Nucleus
- B.Mitochondria
- C.Chloroplast
- D.Ribosome
Show answer and explanation
Answer: B. Mitochondria
Mitochondria carry out cellular respiration, which produces most of the cell’s ATP.
Question 5 · Scientificinvestigation
What is the dependent variable in a study measuring plant growth by sunlight exposure?
- A.Amount of sunlight
- B.Type of plant
- C.Plant growth
- D.Size of the pot
Show answer and explanation

Question 6 · Managingtimeandpressure
Which of the following is an effective concluding sentence?
- A.That was my essay.
- B.In conclusion, I’m done.
- C.Therefore, schools should allow phones as educational tools, not distractions.
- D.So yeah, that’s it.
Show answer and explanation
Answer: C. Therefore, schools should allow phones as educational tools, not distractions.
This sentence restates the argument clearly and leaves the reader with a final, persuasive thought. The other choices are informal and add nothing to the essay.
Question 7 · The English Test
Which sentence contains correct subject-verb agreement?
- A.Neither the coach nor the players were late.
- B.The group of students are excited.
- C.The book and the pen is on the desk.
- D.The dogs barks at the mailman.
Show answer and explanation
Answer: A. Neither the coach nor the players were late.
“Players” is the nearer subject in “neither...nor” structure, so “were” is correct.
Question 8 · The Math Test
Which of the following represents a non-linear function?
- A.y = x²
- B.y = 12x − 6
- C.y = −4x + 1
- D.y = 2x + 3
Show answer and explanation
Answer: A. y = x²
y = x² is quadratic, so its graph is a parabola rather than a straight line. The other equations all have the linear form y = mx + b.
Question 9 · Integrationofknowledgeandideas
