Let's Learn About These 10 Obscure

Explanation
Cats are known to be allergic to humans due to a protein called Fel d 1, which is found in their saliva, urine, and skin glands. When cats groom themselves, this protein gets deposited on their fur, causing allergic reactions in some humans. This can lead to symptoms such as sneezing, itching, and watery eyes. While other pets may cause allergies in humans, cats are specifically known for being allergic to humans.

Explanation
While water is essential for survival, consuming too much of it can lead to a condition called water intoxication or hyponatremia. This occurs when the balance of electrolytes in the body is disrupted, diluting the sodium levels in the blood. In severe cases, it can cause brain swelling, seizures, and even death. Therefore, although water is necessary for life, excessive consumption can be harmful.

Explanation
Competitive art used to be a part of the Olympics. In the early years of the modern Olympic Games, there were competitions in various artistic fields including painting, sculpture, architecture, literature, and music. These competitions aimed to celebrate artistic excellence alongside athletic achievements. However, competitive art was later discontinued as the focus of the Olympics shifted primarily towards sports.

Explanation
The brain is composed mostly of fat, specifically a type of fat called lipids. These lipids make up the cell membranes in the brain, which are crucial for its overall structure and function. Additionally, fat also plays a role in insulating and protecting the brain, as well as providing a source of energy. While muscles, nerves, and water are all important components of the brain, fat is the primary constituent.

Explanation
The moon is said to be slowing the Earth's rotation. This is due to the tidal forces exerted by the moon on the Earth's oceans. As the moon's gravitational pull affects the water on Earth, it creates tidal bulges that cause a slight drag on the rotation of the planet. Over time, this drag slows down the Earth's rotation.

Explanation
The correct answer is "A million years old". This is because the water on Earth is constantly being recycled through the water cycle, which includes processes such as evaporation, condensation, and precipitation. This means that the water we are currently drinking could have been around for millions of years, as it has been continuously recycled and reused throughout Earth's history.

Explanation
New Orange used to be New York's original name. This name was given by the Dutch when they first settled in the area in the early 17th century. However, in 1664, the English took control of the colony and renamed it New York in honor of the Duke of York. So, New Orange was the original name before it was changed to New York.

Explanation
The answer of 364 suggests that it takes approximately 364 licks to reach the center of a tootsie pop. This answer is based on the popular advertising campaign by Tootsie Roll Industries, where a wise owl claims that it takes three licks to get to the center. However, numerous studies and experiments have been conducted to determine the actual number, with most findings ranging from 252 to 364 licks. Therefore, 364 is a reasonable estimate for the number of licks required to reach the center of a tootsie pop.

Explanation
Ethiopia is the correct answer because it is home to the hottest inhabited place on earth, the Danakil Depression. Located in the Afar region of Ethiopia, this area experiences extremely high temperatures, with an average annual temperature of 94°F (34.4°C) and has recorded temperatures as high as 125°F (51.7°C). The Danakil Depression is known for its harsh and inhospitable environment, including active volcanoes, sulfur springs, and salt flats, making it one of the hottest and most extreme places on the planet.
