Questions with solutions
  1. 1. సరైన సమాధానాన్ని ఎంచుకోండి.

    What is different about real history?

    A movie shows people running away from a living T. rex.

    • T. rex lived long before humans appeared.
    • Early humans hunted T. rex with simple tools.
    • T. rex disappeared shortly after the first humans appeared.
    Show solution
    • T. rex lived long before humans appeared.

    Movies sometimes mix time periods. T. rex died out millions of years before humans appeared.

    What did Triceratops mainly eat?

    Triceratops had three horns, a large head, and a sharp beak.

    • Other dinosaurs
    • Plants
    • Fish
    Show solution
    • Plants

    Its horns did not make it a meat eater. Its beak cut plants, and its teeth broke them into smaller pieces.

    Which animals belong to the dinosaur group that survives today?

    Most dinosaur groups died out long ago, but one group is still alive.

    • Lizards
    • Crocodiles
    • Birds
    Show solution
    • Birds

    Birds developed from small meat-eating dinosaurs. A sparrow is part of the dinosaur family tree.

    What were pterosaurs?

    Pterosaurs had wings and lived at the same time as many dinosaurs.

    • Flying reptiles related to dinosaurs
    • Dinosaurs with wings made of feathers
    • Early birds with unusually large beaks

    Living at the same time does not make animals members of the same group.

    Show solution
    • Flying reptiles related to dinosaurs

    Pterosaurs were a separate group. Their wings were made of skin rather than feathers.

    What do fossils tell us about the real animal's height?

    Movies often show Velociraptor standing as tall as an adult person.

    • It stood much taller than an adult person.
    • It stood about as tall as an adult person.
    • It stood much shorter than an adult person.
    Show solution
    • It stood much shorter than an adult person.

    Real Velociraptor stood roughly knee-high. Its long tail made it much longer than it was tall.

    Which picture of dinosaur life fits these discoveries?

    Dinosaur fossils occur in rocks formed in ancient deserts as well as forests.

    • All dinosaurs lived in wet swamps.
    • Different dinosaurs lived in different environments.
    • Dinosaurs could live only beside the ocean.
    Show solution
    • Different dinosaurs lived in different environments.

    Movie jungles show only one possible setting. Dinosaurs lived in many kinds of places.

    What does this discovery tell us about feathers?

    A small dinosaur fossil has feathers, but its arms were too short for flight.

    • Having feathers did not always mean an animal could fly.
    • Every dinosaur with feathers could fly.
    • Feathers appeared only after dinosaurs died out.
    Show solution
    • Having feathers did not always mean an animal could fly.

    Feathers can also help keep an animal warm. Flight is not their only use.

  8. 8. సరైన సమాధానాన్ని ఎంచుకోండి.

    Could these two dinosaurs have met in the wild?

    Stegosaurus lived in the Jurassic period. T. rex lived much later, in the Cretaceous period.

    • Yes, because all dinosaurs lived at the same time.
    • Yes, if they lived beside the same river.
    • No, because they lived at different times.

    Compare the time periods, not the places.

    Show solution
    • No, because they lived at different times.

    The dinosaur age lasted a very long time. Many famous dinosaurs never shared the same world.

    Which event does this evidence support?

    Scientists found a huge impact crater in Mexico and material from the impact in a rock layer around the world.

    • A long ice age dug out the crater.
    • A large asteroid hit Earth.
    • A series of volcanoes formed the impact crater.
    Show solution
    • A large asteroid hit Earth.

    The impact sent dust into the sky. Less sunlight damaged food supplies and helped cause a mass extinction.

    How do many buried bones become fossils?

    Many dinosaur fossils feel more like rock than fresh bone.

    • Minerals fill spaces or replace material in the bones.
    • Heat melts the bones into new rock.
    • The bones dry out and remain completely unchanged.
    Show solution
    • Minerals fill spaces or replace material in the bones.

    Water underground can carry minerals into buried bones. This process can preserve their shape for millions of years.

    What does this fossil show about the dinosaur's teeth?

    A dinosaur jaw has a small new tooth growing below an older tooth.

    • It had only one set of teeth for its whole life.
    • It was losing all its teeth permanently.
    • New teeth could replace older teeth.
    Show solution
    • New teeth could replace older teeth.

    Many dinosaurs replaced their teeth throughout their lives. People normally have only two main sets.

    How did these dinosaurs probably hold their tails while walking?

    Many dinosaur trackways show clear footprints but no marks from a tail.

    • They dragged their tails behind them.
    • They held their tails above the ground.
    • They rested their weight on their tails with each step.

    Think about what would leave a mark beside the footprints.

    Show solution
    • They held their tails above the ground.

    Old pictures often show dragging tails. A raised tail could help a two-legged dinosaur balance.

    What can these rings help scientists estimate?

    Some dinosaur bones contain growth rings, a little like the rings inside tree trunks.

    • How old the animal was when it died
    • How many meals the animal ate
    • How many eggs the animal laid
    Show solution
    • How old the animal was when it died

    Growth can slow during part of the year, leaving a line inside the bone.

    What do these marks show on their own?

    Scientists find T. rex tooth marks on the bones of a plant-eating dinosaur.

    • The T. rex must have killed this animal itself.
    • T. rex only ate animals that were already dead.
    • The T. rex may have bitten it before or after it died.

    A bite mark does not tell us exactly when the bite happened.

    Show solution
    • The T. rex may have bitten it before or after it died.

    Many meat-eating animals both hunt and eat animals they find already dead. Bite marks alone cannot separate those behaviors.

    How certain are we about its exact sound?

    A movie gives a T. rex a deep, lion-like roar.

    • Its size proves that it roared like a lion.
    • Its exact voice is still unknown.
    • Its teeth tell us exactly how its roar sounded.
    Show solution
    • Its exact voice is still unknown.

    Living relatives, such as birds and crocodiles, offer clues about possible sounds. A movie roar is still a creative choice.
