Sample Questions
Seema wants to take medicine because she has a headache but no elder is at home. What should she do?
Show answer
Wait for an elder to come home and then inform them
Step 1: Different medicines are made for different illnesses and for different ages and body weights. Step 2: Taking the wrong medicine or the wrong amount can be very dangerous and can even poison the body. Step 3: A child should NEVER take medicine on their own without the guidance of an adult or a doctor. Step 4: Waiting for an elder ensures that the right medicine is given in the right amount. Step 5: Taking double medicine is especially harmful as even the right medicine becomes dangerous in large amounts.
Why are red and green colours used in traffic lights?
Show answer
Because they can be seen clearly from far away
Step 1: Traffic lights are placed high up on roads so that drivers and pedestrians can see them from a distance. Step 2: Red and green are colours with long wavelengths in light, which means they can travel further and remain visible even in fog, rain, or bright sunlight. Step 3: Drivers need to see the signal from far away so they have enough time to slow down or stop safely. Step 4: If the signal could only be seen from very close, vehicles would not have enough time to brake, causing accidents. Step 5: This is why red and green are specifically chosen for traffic lights all over the world.
Ravi leaves his school bag on the floor near the staircase. Why is this dangerous?
Show answer
Someone might trip over the bag and fall down the stairs
Step 1: Objects left on the floor become obstacles that people may not notice, especially if they are in a hurry. Step 2: Near a staircase, tripping is extra dangerous because a person can fall down many steps and get seriously injured. Step 3: This is why the safety rule says never to leave bags, shoes, or toys on the floor. Step 4: Keeping things in their proper place removes these obstacles and reduces the risk of accidents at home or school. Step 5: Stealing and dirty bags are not safety concerns – the real danger is someone getting physically hurt by tripping.
Which of the following is NOT a benefit of regular exercise?
Show answer
It helps us sleep for 20 hours a day
Step 1: Exercise has many important benefits for our body. Step 2: It strengthens our muscles by making them work harder, which builds them up over time. Step 3: Regular exercise keeps the body fit and helps maintain a healthy weight. Step 4: Exercise can help us sleep better at night, but sleeping 20 hours a day is actually unhealthy and not a benefit of exercise. Step 5: The recommended sleep for children is 8 hours, not 20 hours – too much sleep can make a person feel weak and lazy, not fit and healthy.
