True or False Quiz

Example Questions From the Test

• 1An ice cube floats in a glass filled below the rim. If the ice melts without evaporation or spilling, the water level stays essentially the same. Is this accurate?
  • True — the ice vanishes as heat and therefore adds no water to the glass.
  • False — melting always makes the level rise because solid water contains no liquid volume.
  • True — the floating ice already displaces an amount of water equal in weight to the ice.
  • False — the level falls sharply because liquid water weighs less than the same ice cube.
• 2“All bats are blind and rely entirely on echolocation.” Which verdict and explanation are accurate?
  • True — bats lack functioning eyes because echolocation replaces vision completely.
  • False — bats use vision only as newborns and permanently lose it when they begin flying.
  • True — every bat species navigates exclusively by interpreting reflected sound.
  • False — bats can see, and species differ in how much they also use echolocation.
• 3“The year 2100 will be a leap year because it is divisible by 4.” Which response is accurate?
  • False — a century year must be divisible by 400 to be a leap year, and 2100 is not.
  • False — leap years stop occurring after the year 2096.
  • True — divisibility by 4 is the only rule used to determine every leap year.
  • True — every year ending in 00 automatically includes February 29.
