The options can easily be narrowed down to 2 and 3.prata wrote:Because fish look through water, their eyes are very different from a mammal
1. from a mammal
2. from a mammal's
3. from that of a mammal
4. than that of a mammal
5. than is a mammal's
1. Incorrect comparison of eyes with mammal
2. Correct
3. That of a mammal should be those of a mammal since "their eyes" is plural
4. That of a mammal should be those of a mammal since "their eyes" is plural
5. This again has an issue with the number.
