Answer:

A. Temperatures have generally increased over the past 20,000 years.

C. The most recent ten thousand years and 120,000-130,000 years ago were generally warmer than the time interval between them.

Explanation:

Looking at the far right of the graph, one can see that the temperatures have been steadily rising until the graph ends. The time period there is the last 20,000 years until present so it can be said that temperatures have increased for the past 20,000 years.

Also looking again one can see that apart from the past 10,000 years, the last time temperatures were quite high was 120,000 - 130,000 years ago and the period in-between was not as warm.
