Select the correct answer from the list.
Scientists believe that the Select Answer explain why Earth’s Select Answer fluctuated between glacial periods and interglacial periods.
A= low temperatures, sea levels, Milankovitch Cycles, tilt of Earth's axis.
A= sea levels have, low temperatures have, climate has, tilt of Earth's axis has.

The correct answer is: A= low temperatures, sea levels, Milankovitch Cycles, tilt of Earth's axis.
In order to determine the correct answer, we need to understand and analyze the information given in the question. It seems that scientists believe that certain factors are responsible for the fluctuation between glacial periods and interglacial periods on Earth. These factors include low temperatures, sea levels, Milankovitch Cycles, and the tilt of Earth's axis.
Let's examine the given options:
Option A: "low temperatures, sea levels, Milankovitch Cycles, tilt of Earth's axis" - This option correctly mentions the factors that scientists believe contribute to the fluctuation between glacial and interglacial periods.
Option B: "sea levels have, low temperatures have, climate has, tilt of Earth's axis has" - This option is not coherent and does not provide a clear explanation. It does not logically explain why the Earth's carbon fluctuates between glacial and interglacial periods.
Based on this analysis, we can determine that Option A is the correct answer.
To arrive at this conclusion, it is important to carefully read and understand the question and information provided. Additionally, analyzing the options and comparing them to the given information helps in selecting the correct answer.
