bar graph
line graph
pie graph

Explanation:

Bar graphs are good for comparing discrete data. Line graphs are ideal for showing trends over time. Pie graphs are used for showing proportions of a whole. For the first question, most scientific data showing trends over time or relationships are often displayed using line graphs. For the second - given a table with time - related data, a line graph would best show how the variables change over time.

Answer:

First question: line graph
Second question: line graph
