The 6 sample questions as a list
-
Although the rumor about a canceled spring concert made everyone furious, Marcus tried to set his feelings aside and be ______, asking to see the principal's actual email before deciding anything.
A) rational
B) perceptive
C) opinionated
D) hystericalA) rationalCharacter & Behavior
Setting feelings aside and checking the facts before deciding is being rational. Perceptive is tempting, but it means quick to pick up on things, especially how other people are thinking or feeling, and Marcus is weighing evidence, not reading people. -
The museum's X-ray scan led to a startling ______: beneath the famous harbor painting lay an earlier, hidden portrait that no one had known about for two centuries.
A) phenomenon
B) revelation
C) catastrophe
D) misconceptionB) revelationThinking & Knowing
A hidden portrait unknown for two centuries, suddenly made known, is a revelation. Phenomenon is tempting because the find is unusual, but a phenomenon is an event people can notice or study, not a secret brought to light. -
Rebuilding the flooded library by hand was an enormous ______, requiring hundreds of volunteers, two summers of weekend work and thousands of donated books.
A) ploy
B) enterprise
C) upheaval
D) catastropheB) enterpriseActions & Effort
A big, difficult project like this one, with hundreds of volunteers pitching in, is an enterprise. Upheaval is tempting because a flood brings great disorder, but an upheaval is a sudden shake-up that turns things upside down, not the hard work of setting things right. -
Unlike the sleepy old museum it replaced, the new science center feels ______, with exhibits that change every month and staff who invent fresh hands-on activities each week.
A) dynamic
B) dilapidated
C) erratic
D) stagnantA) dynamicChange & Growth
Constant change and a steady flow of fresh ideas make the center dynamic. Erratic is tempting because things keep changing, but erratic means unpredictable, and exhibits that change every month follow a regular plan. -
To prove the cookie stand was a ______ business under city rules, the Okoro sisters showed the inspector their permit and their receipts for every bag of flour.
A) advantageous
B) fraudulent
C) legitimate
D) reputableC) legitimateQuality & Judgment
A permit shows the stand is allowed by the rules: legitimate. Reputable is tempting, but a reputable business is trusted because of a long good record, and a permit shows only that the stand is allowed. -
When the music box stopped playing, the jeweler opened its back and found that a tiny gear in the winding ______ had slipped out of place.
A) mechanism
B) implement
C) infrastructure
D) arrayA) mechanismNature & Time
The working parts that make a music box play are its mechanism. Implement is tempting because a gear is equipment, but an implement is a tool, such as a rake, not the inner works of a machine.
