Sample Practice Test Questions

General Science

When compared to eukaryotic cells, prokaryotic cells are:

less complex

Cells are classified into one of two groups based on whether or not they have a nucleus. Eukaryotic cells have a nucleus, prokaryotic cells do not have a nucleus and therefore have a less complex structure than eukaryotic cells.

Shop Information

You've bored a large hole in a piece of wood to insert a doorknob. Which of these tools would you use to smooth the edges of the hole?

rasp

Files consist of diagonal rows of fine teeth and are used for fine finishing work to smooth, polish, or shape objects. Rasps are files with larger teeth that are used for coarse finishing work. Both files and rasps are designed to be inserted into detachable handles.

Electronics Information

Silver and gold are among the most highly conductive elements. Why is copper used much more often as a conductor in electrical circuits?

all of these

All conductors have resistance and the amount of resistance varies with the element.  But, resistance isn't the only consideration when choosing a conductor as the most highly conductive elements like silver and gold are also more expensive and more brittle than slightly less conductive elements like copper. A balance needs to be struck between the electrical qualities of a material and its cost and durability.

Mechanical Comprehension

The standard unit of energy is the:

Joule

The Joule (J) is the standard unit of energy and has the unit \({kg \times m^2} \over s^2\).

General Science

Which of the following would be used in eye glasses to correct farsightedness?

convex lens

Unlike curved mirrors that operate on the principle of reflection, lenses utilize refraction. A convex lens is thicker in the middle than on the edges and converges light while a concave lens is thicker on the edges than in the middle and diffuses light. A common use for curved lenses is in eye glasses where a convex lens is used to correct farsightedness and a concave lens is used to correct nearsightedness.

General Science

Blood is circulated throughout the body via:

arterioles

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
The flighty Caroline could not be troubled with mundane tasks such as paying her bills.
commonplace
Practical, ordinary.
Word Knowledge
Audrey used her innocent baby brother as a scapegoat for the missing cookies.
dupe
Someone who bears the blame for others.
Math Knowledge
19

If a = 4, b = 2, c = 9, and d = 4, what is the perimeter of this quadrilateral?

19

Perimeter is equal to the sum of the four sides:

p = a + b + c + d
p = 4 + 2 + 9 + 4
p = 19

General Science

The Earth's rocks fall into three categories based on how they're formed. Which of the following is formed by the gradual depositing of small rocks?

sedimentary

The Earth's rocks fall into three categories based on how they're formed. Igneous rock (granite, basalt, obsidian) is formed from the hardening of molten rock (lava), sedimentary rock (shale, sandstone, coal) is formed by the gradual despositing and cementing of rock and other debris, and metamorphic rock (marble, slate, quartzite) which is formed when existing rock is altered though pressure, temperature, or chemical processes.
