1. 1In Aesop's Belling the Cat, mice celebrate a proposal to hang a bell on their enemy. An old mouse then asks who will attach it. What problem does his question reveal?

   1. A.The plan lacks a way to be carried out safely.Correct answer: A
   2. B.The plan gives the cat too little warning.
   3. C.The plan requires the mice to stop listening.
   4. D.The plan depends on the cat losing its hearing.

   Explanation: The old mouse asks, "But let me ask one question: Who will bell the Cat?" His question exposes the dangerous implementation task left unresolved by the attractive proposal. It does not question whether a ringing bell could warn the mice.

2. 2A classroom project uses 2/3 yard of ribbon for a display and 1/4 yard for a label. How much ribbon does the project use in total?

   1. A.3/7 yard
   2. B.11/12 yardCorrect answer: B
   3. C.3/12 yard
   4. D.1/6 yard

   Explanation: The handbook explains, "convert the individual fractions to equivalent fractions with a common denominator." Here, 2/3 = 8/12 and 1/4 = 3/12, giving 11/12 yard. Adding denominators would incorrectly give 3/7.

3. 3Which sequence correctly describes the creation of the Declaration of Independence in 1776?

   1. A.Delegates sign the parchment; Jefferson drafts; Congress adopts.
   2. B.Congress adopts; delegates sign the parchment; Jefferson drafts.
   3. C.Jefferson drafts; Congress adopts; delegates begin signing the parchment.Correct answer: C
   4. D.Jefferson drafts; delegates sign the parchment; Congress adopts.

   Explanation: The National Archives states, "The Continental Congress adopted the Declaration of Independence on July 4, 1776." Its introduction places Jefferson’s draft in June and the beginning of parchment signing on August 2. Drafting therefore preceded adoption, which preceded the signing of that parchment.

4. 4Which statement is a testable scientific hypothesis about paper towels?

   1. A.Brand A has the most attractive package.
   2. B.All households ought to buy Brand A.
   3. C.Brand A is the best possible towel.
   4. D.A sheet of Brand A absorbs more water than an equal-sized sheet of Brand B.Correct answer: D

   Explanation: NASA describes a hypothesis as "a statement that an experiment can test". Equal-sized sheets can be compared by measuring absorbed water. The other statements express preferences, advice, or an undefined overall judgment rather than a measurable prediction.

5. 5A fox repeatedly tries and fails to reach ripe grapes, then leaves calling them sour and worthless. Which interpretation of the fox's change in attitude is best supported by this sequence?

   1. A.He has discovered that the grapes are unripe.
   2. B.He dismisses something because he cannot obtain it.Correct answer: B
   3. C.He has decided to save the grapes for someone else.
   4. D.He prefers waiting until the grapes fall naturally.

   Explanation: The fable concludes, "There are many who pretend to despise and belittle that which is beyond their reach." The fox disparages the grapes after failing to reach them; the story provides no tasting or new evidence about their quality.

6. 6A craft table has 3/4 pound of clay. Each complete model uses 1/8 pound. How many complete models can be made?

   1. A.3
   2. B.4
   3. C.8
   4. D.6Correct answer: D

   Explanation: The handbook states, "When dividing one fraction by another, first invert the divisor fraction and then multiply." Thus (3/4) ÷ (1/8) = (3/4) × 8 = 6 models. Multiplying by 1/8 instead would not find the number of portions.

7. 7The Declaration of Independence includes a grievance against Britain for imposing taxes without the colonists' consent. What political objection does that grievance express?

   1. A.Taxes were being imposed without the colonists' agreement.Correct answer: A
   2. B.The colonists believed every government should abolish all taxes.
   3. C.Parliament had transferred all taxing authority to colonial assemblies.
   4. D.The colonists wanted the king to collect taxes without Parliament.

   Explanation: The Declaration’s grievance reads, "For imposing Taxes on us without our Consent:" The authors challenge taxation without consent; the statement does not reject every tax or advocate unilateral royal taxation.

   Reference: National Archives — Declaration of Independence (1776) — Declaration transcript, grievance beginning For imposing Taxes

8. 8Students test how salt concentration affects seed germination. Which setup best isolates the effect of salt concentration?

   1. A.Use the same seed type, temperature, and light while varying salt concentration.Correct answer: A
   2. B.Change both seed type and salt concentration between the groups.
   3. C.Keep salt concentration the same while changing light exposure.
   4. D.Give each salt group a different temperature and amount of water.

   Explanation: NASA advises, "Define the parts of your experiment that will not change. These are called controls." Holding other relevant conditions constant lets the students compare salt concentrations. Changing additional factors confounds the comparison; keeping salt fixed does not test its effect.

9. 9In Aesop's The Lion and the Mouse, the lion spares a mouse who promises repayment. Later, the lion is trapped in a hunter's net. The mouse bites through a rope and frees him. How does the rescue relate to the earlier promise?

   1. A.It shows that the mouse had set the trap herself.
   2. B.It shows that the lion has forgotten the mouse.
   3. C.It fulfills a promise the lion had considered unlikely.Correct answer: C
   4. D.It prevents the mouse from keeping her promise.

   Explanation: The text states, "Running to one of the great ropes that bound him, she gnawed it until it parted, and soon the Lion was free." The mouse repays the lion by freeing him, reversing his earlier amusement at the idea that she could help.

10. 10Membership in a school club increases from 80 students to 100 students. What is the percent increase?

    1. A.25%Correct answer: A
    2. B.20%
    3. C.80%
    4. D.125%

    Explanation: The handbook directs, "Compute percent differential by dividing the difference by the original value, multiplying by 100, and adding the percent symbol." The increase is 20, so 20/80 × 100 = 25%. Dividing by the new membership gives the incorrect 20%.
