Answer:
300,000 is less than 352,000
Step-by-step explanation:
Numbers are compared left to right. The number with a digit in the highest-place-value place is largest. If both numbers have a digit in that place, the number with the largest digit is largest. If the digits are the same (as here), the comparison proceeds to the next place to the right, and the process is repeated.
Both numbers have 3 in the hundred-thousands place, so the number with the largest ten-thousands digit is the largest. That number is 352,000, which has a 5 in the ten-thousands place, where the other number has a 0.

Since these numbers are "years ago," the number 352,000 refers to an older (earlier) stage.
