Explicación

## Step 1The question is asking for the time span that represents the earliest 88% of geologic time. This is a multiple-choice question, and the options are Phanerozoic, Chomesozoic, Precambrian, and Paleozoic.## Step 2The Phanerozoic, Paleozoic, and Mesozoic eras are relatively recent in geological terms, spanning the last 541 million years. This is a very small fraction of the Earth's history.## Step 3The Precambrian, on the other hand, represents the time before the Cambrian period, which is known for the rapid diversification of multicellular life. The Precambrian spans from the formation of Earth about 4.6 billion years ago to the advent of hard-shelled creatures almost 541 million years ago.## Step 4Given that the Precambrian spans such a vast period of time, it is reasonable to conclude that it represents the earliest 88% of geologic time.
