Question

1.which animal weighs about the same as 1,500 adult humans?
a. blue whale
b. african elephant
c. polar bear
d. giraffe

Explanation:

To determine which animal weighs about the same as 1,500 adult humans, we analyze the average weight of each animal:

• A blue whale can weigh around 150,000 - 200,000 kilograms. The average adult human weighs about 62 - 80 kilograms. 1,500 adult humans would weigh approximately 1,500 * 70 = 105,000 kilograms (using an average of 70 kg). A blue whale's weight is in a range that can match this.
• An African elephant weighs around 2,000 - 6,000 kilograms, much less than the weight of 1,500 humans.
• A polar bear weighs around 350 - 700 kilograms, far less.
• A giraffe weighs around 800 - 1,900 kilograms, also much less.

So the blue whale is the animal whose weight is about the same as 1,500 adult humans.

Answer:

A. Blue Whale
