Question

1. according to the passage, one difference between the smilodon and the tiger is ______.

a. the size of their teeth
b. the size of their ears
c. the kind of food eaten
d. the length of time they lived on earth

Explanation:

To solve this, we analyze each option:

• Option a: Smilodon (saber - toothed cat) is known for its large, saber - like teeth, while tigers have different - sized teeth. This is a likely difference.
• Option b: There's no significant or well - known difference in ear size between smilodon and tigers as a defining difference.
• Option c: Both are carnivores, so the kind of food (meat) is similar.
• Option d: While smilodon is extinct and tigers are extant, the "length of time they lived" is a broad concept and not as direct a difference as tooth size.

Answer:

a. the size of their teeth
