Question

ice core samples help scientists understand past _____.
○ a. flora
○ b. animal behaviors
○ c. human activities
○ d. climate

which is an example of data collection in polar research?
○ a. animal tracking for hunting
○ b. tourism growth
○ c. polar ship navigation
○ d. monitoring ice thickness

Explanation:

First Question:

Ice core samples are analyzed to study past climate conditions (like temperature, greenhouse gas levels). Flora, animal behaviors, or human activities aren't the primary focus of ice core analysis. So the correct option is d.

Monitoring ice thickness is a scientific data collection method in polar research (to study climate change, ice dynamics). Animal tracking for hunting is not research - related, tourism growth is a socioeconomic study, and polar ship navigation is logistical, not data collection for research. So the correct option is d.

Answer:

d. Climate
