GED COMPREHENSIVE FINAL EXAM
2026/2027 QUESTIONS AND ANSWERS
1. A cylindrical tank has a radius of 4 meters and a height of 10 meters. If the tank is filled to
75% of its capacity, what is the volume of the water? (Use 3.14 for π)
A. 502.4 cubic meters
B. 150.72 cubic meters
C. 125.6 cubic meters
D. 376.8 cubic meters
Answer: D
Conceptual Explanation: The volume of a cylinder is V = πr²h. So, V = 3.14 * 4² * 10 = 3.14
* 16 * 10 = 502.4. 75% of this volume is 502.4 * 0.75 = 376.8.
2. In a genetics experiment, a pea plant with genotype ‘Tt’ is crossed with another ‘Tt’ plant.
What is the probability that the offspring will have the recessive phenotype?
A. 1
B. 0.5
C. 0.75
D. 0.25
,Answer: D
Conceptual Explanation: The cross of Tt x Tt results in genotypes TT, Tt, Tt, and tt. The
recessive phenotype only occurs in the ‘tt’ genotype, which represents 1 out of 4
possibilities (25%).
3. Which sentence uses the subjunctive mood correctly to express a wish or a hypothetical
situation?
A. I wish I was able to attend the ceremony.
B. If he was here, he would know what to do.
C. It is essential that she is informed immediately.
D. If I were you, I would reconsider the offer.
Answer: D
Conceptual Explanation: The subjunctive mood for hypothetical situations uses ‘were’
even for singular subjects, as in ‘If I were you’.
4. What was the primary purpose of the Federalist Papers?
A. To argue against the inclusion of a Bill of Rights.
B. To convince the states to declare independence from Britain.
C. To outline the grievances against King George III.
D. To explain and encourage the ratification of the US Constitution.
Answer: D
, Conceptual Explanation: The Federalist Papers were a series of essays written by
Alexander Hamilton, James Madison, and John Jay to promote the ratification of the United
States Constitution.
5. Solve for x: 3(x - 4) + 2x = 8x - 15
A. x = -3
B. x = -1
C. x = 3
D. x = 1
Answer: D
Conceptual Explanation: Distribute: 3x - 12 + 2x = 8x - 15. Simplify: 5x - 12 = 8x - 15.
Subtract 5x: -12 = 3x - 15. Add 15: 3 = 3x. Therefore, x = 1.
6. Which of the following is a result of the Earth’s tectonic plates moving apart at a divergent
boundary?
A. Deep-sea trenches
B. Mid-ocean ridges
C. Mountain ranges like the Himalayas
D. Subduction zones
Answer: B
