Question

student 1 writes:the protective mother polar bear has many jobs to complete to make sure her baby cubs are safe and well taken care of. student 2 writes: the first thing the mother polar bear does to keep the babies safe is dig a maternity den. the mother polar bear is really big and does lots of stuff during the day. one thing the mother polar bear does to feed herself is to hunt before sunrise. for example, the mother polar bear digs a maternity den so they have a safe place to live.

Explanation:

Student 1 mentions the mother polar - bear has jobs to keep cubs safe. The correct option should elaborate on those jobs. The first option specifically states the first job of the mother polar - bear to keep babies safe (digging a maternity den), which is in line with the context. The second option just says she is big and does stuff without focusing on cub - safety. The third option is about the mother feeding herself, not about cub - safety. The fourth option is a bit redundant as it just re - states the example of digging a den without adding new information about the jobs related to cub - safety as effectively as the first option.

Answer:

The first thing the mother polar bear does to keep the babies safe is dig a maternity den.
