Answer 1

To order the events chronologically from earliest to latest, we would consider the following sequence based on what we know about Earth's history:

1. Single-celled organisms increase atmospheric methane concentrations. - Early life forms, like Archaea, produced methane.
2. Photosynthesizing bacteria release oxygen into the sea. - Cyanobacteria began photosynthesis, releasing oxygen.
3. Oxygen concentrations increase in the atmosphere. - As photosynthesis increased, oxygen began to accumulate in the atmosphere.
4. Many new animal species evolve. - With increased oxygen, more complex life forms, including animals, began to evolve.

Given this understanding, 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 third option fits this sequence correctly:

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.
