Questions and Answers
  • 1. 

    In which of these seasons will you see a rainbow more often?

    • A.

      Summer

    • B.

      Monsoon

    • C.

      Winter

    • D.

      Rainbow can be seen at all times even at night

    Correct Answer
    B. Monsoon
    Explanation
    During the monsoon season, there is a higher chance of seeing a rainbow compared to other seasons. This is because the monsoon season is characterized by frequent rain showers and thunderstorms, which create the ideal conditions for the formation of rainbows. Rainbows occur when sunlight is refracted, reflected, and dispersed by raindrops in the atmosphere, and the abundance of rain during the monsoon season provides more opportunities for this phenomenon to occur.

    Which of these grows from a seed?

    • A.

      Ant

    • B.

      Donkey

    • C.

      Grass

    • D.

      TV

    • E.

      Caterpillar

    Correct Answer
    C. Grass
    Explanation
    Grass grows from a seed. Seeds are the reproductive structures of plants, and grass is a type of plant that reproduces through seeds. The seed contains the necessary genetic information and nutrients for the plant to develop and grow. Once the seed is planted in the soil and provided with the right conditions such as water and sunlight, it germinates and starts to grow into a grass plant. Therefore, grass is the correct answer as it is the only option that undergoes seed germination and growth.

    Which material is got from animals and is used to make clothes?

    • A.

      Silk

    • B.

      Iron

    • C.

      Cotton

    • D.

      Wax

    Correct Answer
    A. Silk
    Explanation
    Silk is a material that is obtained from animals, specifically from the cocoons of silkworms. It is widely used in the textile industry to make clothes due to its smooth and luxurious texture. Silk is known for its strength, durability, and natural sheen, making it a popular choice for high-quality garments. It is a natural protein fiber that is lightweight and breathable, providing comfort and elegance to the wearer.

    Fuel is used up to give energy in order to make things work. Petrol is a type of fuel used in vehicles to make them run. which of these is also a fuel?

    • A.

      Water used in a bath

    • B.

      Food eaten by a person

    • C.

      Air pumped in cycle tyres

    • D.

      Steam given out by pressure cooker

    Correct Answer
    B. Food eaten by a person
    Explanation
    Food eaten by a person is also a fuel because it provides the body with energy. When we eat food, it is broken down by our digestive system into nutrients, which are then converted into energy through various metabolic processes. This energy is used by our body to carry out essential functions and activities. Therefore, just like petrol fuels vehicles, food fuels our body.

    In order to have a non- stop flight, a plane has to be given fuel in the middle of the flight.  which of these is necessary for mid-air refueling to happen?

    • A.

      One plane should be smaller than the other

    • B.

      The planes should be flying above the clouds

    • C.

      Planes should be flying as fast as each other (same speed)

    • D.

      One plane should be flying upwards and the other downwards

    Correct Answer
    C. Planes should be flying as fast as each other (same speed)
    Explanation
    Planes should be flying as fast as each other (same speed) in order for mid-air refueling to happen. This is because the process of refueling requires both planes to maintain a steady position relative to each other. If one plane is faster than the other, it would be difficult to align the fueling apparatus and maintain a stable connection. Therefore, having both planes flying at the same speed ensures a successful mid-air refueling operation.

    Shushila has brown eyes. The following people in her family have brown eyes whom could she have got her brown eyes from?

    • A.

      Her niece

    • B.

      Her sister

    • C.

      Her daughter

    • D.

      Her grandmother

    Correct Answer
    D. Her grandmother
    Explanation
    Shushila could have inherited her brown eyes from her grandmother. Eye color is determined by a combination of genes from both parents, and it is possible for traits to skip a generation. Since her niece, sister, and daughter are all in the same generation as Shushila, it is less likely for them to be the direct source of her brown eyes. However, her grandmother, who is from a previous generation, could have passed down the genes for brown eyes to Shushila.

    When a coin is dropped is a glass of water, it will __________.

    • A.

      Float

    • B.

      Sink

    • C.

      Float mid-way

    • D.

      Break the glass

    Correct Answer
    B. Sink
    Explanation
    When a coin is dropped in a glass of water, it will sink. This is because the density of the coin is greater than the density of water. Objects with a higher density than the liquid they are placed in will sink.

    The change of a substance from the liquid state to the gaseous state is called

    • A.

      Evaporation

    • B.

      Condensation

    • C.

      Sublimation

    • D.

      Filtration

    Correct Answer
    A. Evaporation
    Explanation
    Evaporation is the process in which a substance changes from its liquid state to its gaseous state. This occurs when the particles of the substance gain enough energy to overcome the forces of attraction between them and escape into the air. Unlike boiling, which occurs at a specific temperature, evaporation can happen at any temperature. It commonly occurs when a liquid is exposed to air, causing the liquid to gradually disappear over time.

    The change of a substance from the gaseous state to the liquid state is called

    • A.

      Condensation

    • B.

      Decantation

    • C.

      Sedimentation

    • D.

      Evaporation

    Correct Answer
    A. Condensation
    Explanation
    Condensation refers to the process of a substance changing from a gaseous state to a liquid state. This typically occurs when the substance loses heat energy and its particles slow down, causing them to come closer together and form liquid droplets. Condensation commonly occurs when warm air comes into contact with a cooler surface, such as when water vapor in the air condenses on a cold window.

    The change of a substance from the solid state to the gaseous state is called

    • A.

      Sublimation

    • B.

      Evaporation

    • C.

      Melting

    • D.

      Filtration

    Correct Answer
    A. Sublimation
    Explanation
    Sublimation is the process in which a substance transitions directly from the solid state to the gaseous state without passing through the liquid state. This occurs when the substance is heated and its vapor pressure exceeds the atmospheric pressure. Evaporation, on the other hand, is the process in which a liquid changes to a gas at its surface. Melting refers to the transition from solid to liquid, and filtration is a method used to separate solid particles from a liquid or gas. Therefore, the correct answer for the given question is sublimation.
