Super Senses

Six times

Step 1: The chapter has a special section about the tiger's amazing senses. Step 2: It clearly states that a tiger can see six times better at night than most humans. Step 3: This helps the tiger hunt in the dark. Step 4: Remember — eagles see four times better than us in the day, while tigers see six times better at night. Step 5: So the correct answer is six times.

By feeling vibrations on the ground

Step 1: The chapter explains that snakes do not have any external ears (no ears we can see from outside). Step 2: Without external ears, snakes cannot hear sounds the way we do. Step 3: Instead, snakes feel the vibrations that travel through the ground. Step 4: The book gives an activity — if you put your ear on a desk and tap it, the sound seems louder because vibrations travel through solid surfaces. Step 5: This is exactly how snakes 'hear' — through ground vibrations, not through ears.

The smell of the other dog's urine or potty

Step 1: Dogs have a very powerful sense of smell — much stronger than humans. Step 2: The chapter tells us that dogs mark out their own area on the road. Step 3: When another dog enters that area, the resident dog can detect the smell of the newcomer's urine or potty. Step 4: This is why you often see dogs sniffing around carefully — they are reading smell messages! Step 5: So smell, not sound or sight, is how dogs recognise other dogs in their territory.

Black and white only

Step 1: The chapter discusses how animals see colours differently from humans. Step 2: It is believed that animals active during the daytime can see some colours. Step 3: However, animals that are awake at night (nocturnal animals) can only see things in black and white. Step 4: This means night animals do not see the beautiful colours we see — everything looks black, white, or shades of grey to them. Step 5: So the correct answer is black and white only.
