1 / 25
Which revision best improves sentence clarity?“Maria realized the car, which she had bought last year, it needed repairs.”
Choice “Maria realized the car needed repairs” removes the unnecessary pronoun “it,” correcting the structure and eliminating redundancy for a clear, grammatically correct sentence.
2 / 25
Choose the correct form:“Neither the players nor the coach ___ ready.”
When subjects are joined by “neither/nor,” the verb agrees with the subject closest to it—“coach,” which is singular, so “is” is correct.
3 / 25
Best placement of a comma?“Before leaving the house I grabbed my jacket.”
Introductory phrases longer than a few words require a comma. The phrase “Before leaving the house” is introductory, so a comma is correctly placed before “I.”
4 / 25
Choose the most concise revision: “Scientists are able to study the stars by using telescopes.”
Option A is active, direct, and concise, eliminating unnecessary phrasing like “are able to” and passive or wordy constructions.
5 / 25
Correct transition? “Many people exercise daily. ____, a balanced diet is also important.”
The second sentence adds supporting information, not contrast, so “Additionally” is the appropriate transitional word for adding related ideas.
6 / 25
Solve: 3x − 7 = 11
Add 7 to get 3x = 18, then divide by 3 to obtain x = 6. Straightforward linear equation solving.
7 / 25
What is the slope of the line through (2,3) and (6,11)?
Slope = (11 − 3) / (6 − 2) = 8/4 = 2. Uses the standard slope formula for two coordinate points.
8 / 25
If f(x) = x² − 4x + 1, what is f(3)?
Substitute x = 3: 9 − 12 + 1 = −2. Evaluating functions involves replacing the input and simplifying carefully.
9 / 25
Which is equivalent to (3x²)(2x³)?
Multiply coefficients (3×2=6) and add exponents on x (2+3=5) to get 6x⁵, following exponent multiplication rules.
10 / 25
What is 30% of 250?
Convert 30% to 0.30, multiply by 250 to get 75. Percent problems require converting to decimals and performing multiplication.
11 / 25
In a passage describing a character as “unyielding,” the word most nearly means:
“Unyielding” means refusing to bend or compromise; closest match is “stubborn” in context of behavior or personality.
12 / 25
If an author’s purpose is to “challenge a common belief,” the tone is likely:
Challenging a belief requires critique or questioning, so a critical, analytical tone best fits the author’s argumentative purpose.
13 / 25
The phrase “a turning point in history” most nearly refers to:
A turning point is a significant moment that alters the direction of events, leading to major and lasting consequences.
14 / 25
If a paragraph focuses on “cause and effect,” it will primarily:
Cause-and-effect structures explain reasons (causes) that lead to specific outcomes (effects) rather than comparing or sequencing events.
15 / 25
If a narrator is unreliable, readers should:
An unreliable narrator presents distorted or biased information, so readers must evaluate events critically instead of trusting fully.
16 / 25
In an experiment, the “control group” is used to:
A control group remains unchanged to provide a baseline comparison, isolating the effects of the independent variable.
17 / 25
The independent variable is the factor:
Independent variables are purposely changed by experimenters to observe their influence on dependent (measured) variables.
18 / 25
A graph showing rapid decrease then leveling off suggests:
Rapid decline followed by a flat line signals that change slows and stabilizes over time, indicating equilibrium or steady state.
19 / 25
DNA primarily stores:
DNA carries encoded instructions for organism growth, structure, reproduction, and inheritance, forming the basis of genetic traits.
20 / 25
The greenhouse effect results from increased:
CO₂ and other greenhouse gases trap heat in Earth’s atmosphere, intensifying warming and altering climate systems globally.
21 / 25
Solve for x: 5x + 2 = 3x + 14
Subtract 3x → 2x + 2 = 14; subtract 2 → 2x = 12; divide → x = 6.
22 / 25
What is √49?
√49 equals 7 because 7×7 = 49.
23 / 25
If a triangle’s angles are 40° and 55°, the third angle is:
Sum of angles = 180°; 180 − (40 + 55) = 85.
24 / 25
(x − 2)(x + 2) =
Difference of squares: (a−b)(a+b)= a² − b² → x² − 4.
25 / 25
Convert 0.25 to a fraction:
0.25 equals 25/100, which simplifies to 1/4.
