Answer:

Paleozoic

Explanation:

The first insect fossils are dated to the Devonian, but because of the development of the genetics, the scientists have been able to trace the appearance of the first insects in the Ordovician. The insects originated from the crustaceans. Initially they were walking on land, but they hadn't developed wings. The wings came to develop in some insects in the Devonian, and since than it has gradually became one of their trademark features. It is interesting that the first insects actually appeared at the same time with the first terrestrial plants, and also that they are the first organisms to develop wings and be able to fly.

How were you going to solve the problem brought by earthquakes in South Africa

lisabon 2012 [21]

Ensuring the safety of the people after the earthquake struck would be the main priority. Make sure there would be no occurrence of tsunami before deploying rescue operations. I would immediately deploy all of the necessary health equipment and personnel to the affected areas. Rescue operations must be started also to save those who were trapped by debris. Also the removal of live electrical wires is really important.
