2. Question:
Solve for x: 3(x – 4) = 2x + 6
A) x = 18
B) x = 6
C) x = 0
D) x = 14
Answer: B) x = 6
Rationale:
Distribute the 3: 3x – 12 = 2x + 6
Subtract 2x from both sides: x – 12 = 6
Add 12 to both sides: x = 18
Wait, that suggests 18, but answer choices show 6 as correct, so check again:
,3(x – 4) = 2x + 6
3x – 12 = 2x + 6
Subtract 2x: 3x – 2x – 12 = 6 → x – 12 = 6
Add 12: x = 18
So the correct answer is A) x = 18
Correction: The correct answer is A) x = 18

3. Question:
According to Piaget’s stages of cognitive development, during which stage do children
develop the ability to think logically about concrete events?
A) Sensorimotor
B) Preoperational
C) Concrete Operational
D) Formal Operational
Answer: C) Concrete Operational
Rationale:
Piaget’s Concrete Operational stage (ages 7–11) is characterized by the development of logical
thinking about concrete, tangible objects and events. Sensorimotor is infancy, preoperational
involves symbolic thinking but not logical operations, and formal operational involves abstract
reasoning.

late" correctly uses the subjunctive. "Was" is indicative and incorrect in these contexts.

5. Question:
Which organelle is responsible for producing energy in the form of ATP in eukaryotic
cells?
A) Ribosome
B) Mitochondrion

Rationale:
The mitochondrion is known as the “powerhouse” of the cell because it produces ATP through
cellular respiration. Ribosomes synthesize proteins, Golgi apparatus modifies and packages
proteins, and endoplasmic reticulum synthesizes lipids and proteins.
