Question 9 of 10
The Eiffel Tower is taller in summer.
Why, in question 8: Eating a lot of carrots lets a person see in the dark.
It's a myth. Carrots contain beta-carotene, which the body converts into vitamin A, important for vision. A lack of this vitamin causes night blindness, but eating carrots beyond what is needed does not give you sight in the dark.
A story from the Second World War
According to a widely repeated account, the idea spread during the Second World War: the British government said its pilots could see well at night because they ate a lot of carrots, which helped disguise the use of a new radar.
Propaganda also encouraged the public to eat more carrots, which were plentiful in the country during food rationing.
Vitamin A is also found in foods such as liver, eggs, milk, pumpkin, mango and dark green leaves. Excess beta-carotene can make the skin a little orange, an effect that fades when consumption decreases.
Carrots were not always orange. Older varieties were purple, yellow or white, and the orange carrot we know became established in Europe around the 16th and 17th centuries.
