Question

2.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 an adult human (around 60 - 80 kg, so 1,500 humans would be 90,000 - 120,000 kg) and the weights of the animals:

• A Blue Whale can weigh up to 150,000 - 200,000 kg, which is in the range of 1,500 adult humans' combined weight.
• An African Elephant weighs around 5,000 - 7,000 kg, much less than the required range.
• A Polar Bear weighs around 350 - 700 kg, far less.
• A Giraffe weighs around 800 - 1,900 kg, also far less.

Answer:

A. Blue Whale
