Answer 1

To order the events chronologically from earliest to latest, we can follow the sequence of biological and atmospheric changes.

1. Single-celled organisms increase atmospheric methane concentrations. (This could happen early in Earth's history before oxygen production.)
2. Photosynthesizing bacteria release oxygen into the sea. (This began the process of oxygenating the planet.)
3. Oxygen concentrations increase in the atmosphere. (As more oxygen is produced, it gradually fills the atmosphere.)
4. Many new animal species evolve. (The increase in oxygen levels supports the evolution of diverse animal life.)

Therefore, the correct chronological order is:

Single-celled organisms increase atmospheric methane concentrations. Photosynthesizing bacteria release oxygen into the sea. Oxygen concentrations increase in the atmosphere. Many new animal species evolve.

So the correct response is the second option:

Single-celled organisms increase atmospheric methane concentrations. Photosynthesizing bacteria release oxygen into the sea. Oxygen concentrations increase in the atmosphere. Many new animal species evolve.
