The two correct answers that can be determined by reading the geologic time scale are:
- the events that ended major divisions of geologic time
- the number of eras in Earth's history
The geologic time scale provides information about the divisions of time, significant events, and the general structure of Earth's history, including the number of eras. However, while it may indicate the types of life forms present in different eras, it does not provide a comprehensive list of all life forms or the precise age of Earth.
