Sample Practice Test Questions

General Science

What is the body's largest artery?

aorta

The aorta is the body's largest artery and receives blood from the pulmonary vein via the left ventricle. From there, blood is circulated through the rest of the body through smaller arteries called arterioles that branch out from the heart. Finally, blood is delivered to bodily tissues through capillaries.

Word Knowledge
Appalling most nearly means:
dreadful
Inspiring dismay or disgust.
Mechanical Comprehension

The steering wheel of a car is an example of which type of simple machine?

wheel and axle

A wheel and axle uses two different diameter wheels mounted to a connecting axle. Force is applied to the larger wheel and large movements of this wheel result in small movements in the smaller wheel. Because a larger movement distance is being translated to a smaller distance, force is increased with a mechanical advantage equal to the ratio of the diameters of the wheels. An example of a wheel and axle is the steering wheel of a car.

Word Knowledge
Revive most nearly means:
reanimate
To bring back to life.
Electronics Information

Current is the rate of flow of electrons per unit time and is measured in:

amperes

Current is the rate of flow of electrons per unit time and is measured in amperes (A). A coulomb (C) is the quantity of electricity conveyed in one second by a current of one ampere.

Word Knowledge
Punctual most nearly means:
prompt
On time.
Word Knowledge
Induce most nearly means:
incite
To influence or cause.
General Science

During digestion, where is digested food absorbed into the blood stream?

small intestine

The small intestine is where most digestion takes place. As food travels along the small intestine it gets broken down completely by enzymes secreted from the walls. These enzymes are produced in the small intestine as well as in the pancreas and liver. After the enzymes break down the food, the resulting substances are then absorbed into the blood via capillaries in the small intestine walls.

Arithmetic Reasoning

What is c5 x 4c7?

4c12

To multiply terms with exponents, the base of both exponents must be the same. In this case they are so multiply the coefficients and add the exponents:

c5 x 4c7
(1 x 4)c(5 + 7)
4c12

Math Knowledge

Solve 3c + 2c = 9c - 9z + 8 for c in terms of z.

1\(\frac{5}{6}\)z - 1\(\frac{1}{3}\)

To solve this equation, isolate the variable for which you are solving (c) on one side of the equation and put everything else on the other side.

3c + 2z = 9c - 9z + 8
3c = 9c - 9z + 8 - 2z
3c - 9c = -9z + 8 - 2z
-6c = -11z + 8
c = \( \frac{-11z + 8}{-6} \)
c = \( \frac{-11z}{-6} \) + \( \frac{8}{-6} \)
c = 1\(\frac{5}{6}\)z - 1\(\frac{1}{3}\)
