Question 1

Select the answer choice that correctly completes the following:
All mountain lions are blue.
Peter saw a mountain lion.

Accepted Answer

The mountain lion was blue. Answer A is correct because it draws a logical conclusion from the major premise ("all mountain lions are blue") and the minor premise ("Peter saw a mountain lion"). The test-taker must ignore the fact that the major premise is not true. The test-taker must focus only on the logical conclusion from the major and minor premise as given in the question. Answer B is not correct because Peter is not within the class of mountain lions. Answer C is not correct because it simply repeats the major premise. Answer D is not correct because Peter is not within the class of mountain lions.

Question 2

Select the answer choice that correctly completes the following:
All comedians are cynics.
Jerry is a comedian.

Accepted Answer

Jerry is a cynic. Answer D is correct because it completes the logical connection between Jerry and cynics. The statement "Jerry is a comedian" establishes that Jerry is within the class of all comedians. Since the major premise establishes that "all comedians are cynics," Jerry the comedian must also be a cynic. Answers A and B are incorrect because both are too over-inclusive for a logical conclusion (they use the word "all"). Answer C is incorrect because the conclusion is about Jerry's humor and not Jerry.

Question 3

An automobile is to driving as a(n) ________ is to a(n) __________.

Accepted Answer

An automobile is to driving as a boat is to sailing. An automobile is a physical object and driving is an action or motion done with an automobile. Similarly, a boat is an object, and sailing is an action done with a boat. A stake and a pup tent are two related objects-neither word emphasizes an action. Eyeliner is one element used in makeup, again with no action emphasized. A bus is an object that provides transportation, but D is a better answer because "sailing" and "driving" emphasize current action.

Question 4

A statue is to a painting as a(n) ________ is to a(n) _________.

Accepted Answer

A statue is to a painting as a pencil is to a pen. Statues and paintings are different types of artwork, and pencils and pens are different types of writing instruments. Fish and snowflakes have no relationship. An automobile is a device that can be used for transportation-there is no distinction between types within the same category. Although a judge and a legislator are both public officials, Answer A is a better answer because pencils and pens are clearly different types within the same category (writing instruments). Answer D leaves some doubt because, even if a judge and a legislator are both public officials, each has a different role, whereas pens and pencils both have the same purpose as writing instruments.

Question 5

A car is to a tire is as a(n) ________ is to a(n) _________.

Accepted Answer

A car is to a tire is as a book is to a page. The relationship between a car and a tire is that a tire is a part of a car, and the relationship between a book and a page is that a page is a part of a book. Ice and water are two forms of the same substance. An eagle and a falcon are two types of birds. Streets and sidewalks are separate-a sidewalk is not a part of a street.

Question 6

Mountains are to valleys as ________ are to _________.

Accepted Answer

Mountains are to valleys as buildings are to city streets. Both mountains and valleys are different features in a landscape, and buildings and city streets are different features in a cityscape. Islands and peninsulas are both features in ocean environments, but C is a better answer because buildings and city streets contrast high and low areas is a way that is closer to the contrast between mountains and valleys. Blood cells are found inside human beings and do not stand in contrast. The terms "cars" and "automobiles" are different words for the same thing-there is no contrast.

Question 7

Ann states that "All politicians are corrupt, and Senator Miller is a politician. Therefore, Senator Miller is corrupt." After a thorough investigation, Samuel conclusively proves that Congressman Jones is not corrupt. Samuel's proof regarding the Congressman undermines Ann's statement in which of the following ways:

Accepted Answer

By questioning the validity of Ann's premise that "All politicians are corrupt." Ann's premise that "All politicians are corrupt" is her major premise that has general application to all politicians. Samuel's proof regarding the Congressman undermines Ann's major premise because the Congressman is politician, but is not corrupt, bringing into question the validity of Ann's major premise. Answer C is not the best answer because Samuel has not proven that Senator Miller is not corrupt, even though Samuel's undermining of Ann's major premise makes her conclusion less certain. Answer A simply repeats Samuel's proof. Answer B is not correct because Samuel has not proven that Senator Miller is not corrupt.

Question 8

Apple is to orange as ________ is to _________.

Accepted Answer

An apple is to an orange as a sparrow is to a robin. Apples and orange are both fruits, but different types of fruits, and a sparrow and a robin are both birds, but different types of birds. Snow and water are different forms of the same substance (water). A tree is a plant, and soil is not a plant, so the two are not different types of the same thing. Air is a naturally occurring gas, and smog consists of pollutants suspended in the air.

Question 9

Select the answer choice that correctly completes the following:
All human beings are mortal.
Plato is a human being.

Accepted Answer

Plato is mortal. The first sentence is a major premise and establishes a general principle taken as true-that human beings are mortal. The second sentence is a minor premise and establishes that a specific person is a human being. Answer D properly connects the major and minor premises by concluding that Plato (a human being) comes within the general principle (mortality of human beings) established in the major premise.

Question 10

Select the answer choice that correctly completes the following:
All automobile drivers owe a duty of care to others.
Darlene is a driver of an automobile.

Accepted Answer

Darlene owes a duty of care to others. The major premise establishes a duty of care that is owed by all drivers to others, and the minor premise establishes that Darlene is within the class of drivers. Since Darlene is within the class of drivers, she also owes a duty of care to others. Answer A is not correct because the duty is owed to others, not to automobiles. Answer B is not correct because it simply restates the minor premise. Answer D is not correct because it is too broad (uses the term "all"), and because it does not draw a conclusion from the minor premise.

Question 11

At a press conference, a reporter asked a candidate for mayor, "Did you sleep with Annie Actress?" The candidate responded, "Definitely not." Another reporter asked, "Is that false?" The candidate responded, "Yes."
Select the answer choice that correctly describes the candidate's responses:

Accepted Answer

If the candidate's first answer is false, his second answer is true. If the candidate did sleep with Annie Actress, and the candidate falsely answered that he did not do so, then his second answer is true. Answer A is not correct because it adds facts that are not a part of the question. Answer B is incorrect because George's responses cannot both be true. Answer D is incorrect because George's responses cannot both be false.

Question 12

There are two underground passageways with manholes. You must pick one to go through. One manhole is circular and the other is a square. Which do you chose?

Accepted Answer

The manhole with the circular cover. For safety's sake, you pick the circular manhole cover, because this cover cannot fall through its hole. Square manhole covers could fall through diagonally killing you. Tsk tsk tsk.
Key Takeaway: This is a classic brainteaser and we hate it. It doesn't really prove anything, but 3 out of 5 people who worked on this module had it in interviews, so we included it.
Editor's Note: I had a co-worker who always gave this question to undergrads. Very few of them got it, but he judged them more on how they handled the question more than whether they got it.

Question 13

Select the answer choice that correctly describes George's responses in the following:
Jerry: Is Elaine in the apartment?
George: Yes.
Jerry: Is that true?
George: No.

Accepted Answer

If George's first answer is false, his second answer is true. If Elaine is not in the apartment, and George falsely answered that Elaine is in the apartment, then George's second answer is true. Answer A is incorrect because George's responses cannot both be true. Answer C is not correct because it adds facts that are not a part of the exchange between Jerry and George. Answer D is incorrect because George's responses cannot both be false.

Question 14

What type of bonding does a molecule of NaCl display?

Accepted Answer

NaCl is composed of two ions, Na+ and Cl-. Therefore, the molecule displays ionic bonding.

Question 15

What type of bonding does a molecule of O₂ display?

Accepted Answer

A molecule of O2 consists of two oxygen molecules sharing electrons equally. Thus, the molecule displays nonpolar covalent bonding.

Question 16

What molecular geometry does the molecule in this figure display?

Accepted Answer

The molecule in this figure is sulfur tetrafluoride. It contains a middle sulfur atom surrounded by four substituent fluorine atoms and one lone pair of electrons. Therefore, it displays see-saw geometry.

Question 17

What is the expected H-C-H bond angle in a molecule of CH₄?

Accepted Answer

CH4 displays tetrahedral molecular geometry. Therefore, the expected H-C-H bond angle is 109.5 degrees.

Question 18

A colloid made from a liquid dispersing medium and gas dispersed phase is called what?

Accepted Answer

Foams are colloids with a liquid dispersing medium and a gas dispersed phase. An aerosol has a gas dispersing medium and dispersed phase. An emulsion has a liquid dispersing medium and dispersed phase. A sol has a liquid dispersing medium and a solid dispersed phase. A solid foam has a solid dispersed medium and a gas dispersed phase.

Question 19

Which of the following is not true about complex ions?

Accepted Answer

Ligands, the compounds that bind to the central metal atom, always act as Lewis Bases. Lewis Bases donate lone pairs of electrons to the Lewis Acid (the metal ion). All other statements are true.

Question 20

A fixed quantity of a gas undergoes a change in temperature from 100 K to 200 K and a change in pressure from 2 atm to 1 atm. After theses changes, the volume of the gas is

Accepted Answer

The pressure, temperature, and volume of a gas are related by the ideal gas law, PV=nRT. Solving for volume gives the equation V=(nRT/P). The molar quantity of gas (n) is constant, so the equation reduces to V=T/P. In the context of the question, temperature is doubled while pressure is halved, resulting in a four-fold increase in volume.
