Math
1. What is the solution to the equation 2x+5=172x + 5 = 172x+5=17?
A) 5
B) 6
C) 11
D) 12
Answer: B) 6
Rationale:
Subtract 5 from both sides: 2x=122x = 122x=12. Divide both sides by 2: x=6x = 6x=6.
2. Which of the following is the derivative of f(x)=3x4−5x+7f(x) = 3x^4 - 5x +
7f(x)=3x4−5x+7?
A) 12x3−512x^3 - 512x3−5
B) 12x3+512x^3 + 512x3+5
C) 3x3−53x^3 - 53x3−5
D) 4x3−54x^3 - 54x3−5
Answer: A) 12x3−512x^3 - 512x3−5
Rationale:
Using the power rule, derivative of 3x43x^43x4 is 12x312x^312x3, derivative of −5x-5x−5x is
−5-5−5, and derivative of a constant is 0.
Science
,3. What is the primary function of mitochondria in eukaryotic cells?
A) Protein synthesis
B) Energy production
C) DNA replication
D) Photosynthesis
Answer: B) Energy production
Rationale:
Mitochondria are known as the "powerhouses of the cell" because they produce ATP through
cellular respiration.
4. Which of the following best describes Newton's First Law of Motion?
A) For every action, there is an equal and opposite reaction.
B) An object in motion stays in motion unless acted upon by a net external force.
C) Force equals mass times acceleration.
D) Energy cannot be created or destroyed.
Answer: B) An object in motion stays in motion unless acted upon by a net external force.
Rationale:
Newton's First Law (the law of inertia) states that an object will maintain its state of rest or
uniform motion unless a net force acts upon it.
English Language Arts
5. Identify the type of figurative language in the sentence: "The classroom was a zoo."
A) Metaphor
B) Simile
C) Personification
D) Hyperbole
Answer: A) Metaphor
Rationale:
The sentence directly compares the classroom to a zoo without using "like" or "as," which
defines a metaphor.
, 6. Which sentence is grammatically correct?
A) Neither of the students have completed the assignment.
B) Each of the dogs are barking loudly.
C) The group of friends is planning a trip.
D) Me and him went to the store.
Answer: C) The group of friends is planning a trip.
Rationale:
"Group" is a singular collective noun, so it takes a singular verb "is." The other sentences contain
subject-verb agreement errors or improper pronouns.
Social Studies
7. Which event marked the beginning of the American Revolutionary War?
A) The Boston Tea Party
B) The signing of the Declaration of Independence
C) The Battle of Lexington and Concord
D) The Treaty of Paris
Answer: C) The Battle of Lexington and Concord
Rationale:
The first military engagements of the Revolutionary War occurred at Lexington and Concord in
April 1775.
8. What is the primary purpose of the system of checks and balances in the U.S. government?
A) To ensure that the president has ultimate power
B) To prevent any one branch of government from becoming too powerful
C) To speed up the legislative process
D) To allow states to override federal laws
Answer: B) To prevent any one branch of government from becoming too powerful
Rationale:
The system of checks and balances allows each branch of government (executive, legislative,
judicial) to limit the powers of the others, ensuring a balance.
