Answer 1

The correct chronological order of events from earliest to latest is:

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

However, this exact order isn't present in the options you've provided. The closest correct sequence based on the typical understanding of these events is:

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

This is not in your options, but understanding the typical events in Earth's history can help clarify the sequencing.
