Answer:
Fossils are the dead decay of plants and organisms that were buried about millions of years ago, under certain conditions. These fossils belong to different time periods in geological history. Some of the major events that occurred in the geological past, based on the fossil evidence are as follows-
(1) The earliest fossil was found in the rocks of Western Australia that were about 3.4-3.5 billion years old.
(2) The 'great oxidation event' took place almost 2.4 billion years back during which the oxygen started to form in the atmosphere. This led to the occurrence of first photosynthetic bacteria.
(3) The first eukaryotic and multicellular organisms came into the picture by about 2 billion years and 900 million years back respectively.
(4) The corals were initially formed about 580 million years back.
(5) Then the trilobites first appeared during the Cambrian period (about 540 million years back) and they were the most dominating species during that time.
(6) The dinosaurs were the giant, dominated species that first appeared in the Triassic age about 240 million years back.
(7) The first human fossil dated back to about 4 million years.

Answer:
C. The boys trapped in the cave showed amazing mental strength, despite the strain the traumatic experience likely put on their minds and bodies.
Explanation:
The central idea of the text is to present the effects that a traumatic situation can cause in the lives of those who have gone through it. In this case, the boys, after having a very impactful experience and that marked their lives forever, developed an admirable control and mental strength that accompanied them during the next events that occur in their lives, having a strong influence in all events.
