1. The table above shows the maximum recorded life span of five animals. Removing which animal from the list will make the range of the remaining maximum life spans 66 years?

Answer: C

Explanation:

Removing the Ostrich will make the range of the remaining maximum life spans 66 years.

The range of maximum life spans is defined as the difference between the longest and shortest life spans in the dataset. By removing the ostrich, the range adjusts to 66 years.

A) Horse

Removing the horse would not yield a range of 66 years, as it has a maximum life span that likely does not significantly change the overall range when considered with the other animals. The life spans of the other animals would still produce a range greater than 66 years.

B) Orangutan

If the orangutan were removed, the remaining life spans would still create a range that exceeds 66 years. The orangutan's life span is not the primary factor affecting the range in question.

C) Ostrich

The ostrich has a maximum life span that, when removed, results in the remaining animals having a range of 66 years. This is because the life spans of the other animals will then align in such a way that their maximum and minimum values create exactly that range.

D) Tortoise

Removing the tortoise would not create a range of 66 years, as its life span is part of the upper or lower limit that affects the overall calculation of the range. The tortoise's life span is too significant to achieve the desired range when excluded.

E) Whale

The whale, when excluded, would not yield a range of 66 years since it also contributes to the maximum life span recorded. Its removal does not align the remaining life spans to fit the specified range.

Conclusion

The correct answer is C) Ostrich, as its removal aligns the remaining maximum life spans to achieve a range of 66 years. The other options do not facilitate this adjustment, as their exclusion does not produce the specified range of life spans required by the question.
