Which of the following animals is likely to weigh closest to 50 pounds?

A. A fully-grown lion
B. An adult zebra
C. A baby giraffe
D. A full-grown kangaroo

To determine which animal is likely to weigh closest to 50 pounds, we can make some educated guesses based on the average weights of these animals. Keep in mind that the weights can vary depending on the specific gender, age, and subspecies of each animal.

Start by gathering information about the average weights of these animals.

A. Fully-grown lions typically weigh between 265 to 420 pounds.
B. Adult zebras usually weigh around 500 to 700 pounds.
C. Baby giraffes can weigh anywhere from 100 to 150 pounds at birth.
D. Full-grown kangaroos vary in weight depending on the species. On average, they can range from 50 to 200 pounds.

From this information, we can eliminate options A (fully-grown lion) and B (adult zebra) as they clearly exceed 50 pounds. Option C (baby giraffe) is also unlikely to weigh closest to 50 pounds since it's already around 100-150 pounds at birth.

This leaves us with option D (full-grown kangaroo). Since kangaroos can range in weight from 50 to 200 pounds on average, it is possible that a full-grown kangaroo might weigh closest to 50 pounds compared to the other options.

Therefore, the answer is D. A full-grown kangaroo is likely to weigh closest to 50 pounds.

To determine which animal is likely to weigh closest to 50 pounds, we need to compare the average weight of each animal.

A. A fully-grown lion: A fully-grown male lion can weigh between 330 to 550 pounds, so it is much heavier than 50 pounds.
B. An adult zebra: An adult zebra can weigh between 500 to 990 pounds, which is also significantly heavier than 50 pounds.
C. A baby giraffe: A baby giraffe typically weighs around 100 to 150 pounds at birth, but they can grow to weigh up to 3,000 pounds as adults. Therefore, a baby giraffe is heavier than 50 pounds.
D. A full-grown kangaroo: A full-grown kangaroo can weigh between 50 to 120 pounds. This weight range includes weights close to 50 pounds, so a full-grown kangaroo is the animal most likely to weigh closest to 50 pounds.

Therefore, option D, a full-grown kangaroo, is the animal that is likely to weigh closest to 50 pounds.
