Air moves from areas of higher temperature to areas of lower temperature. In this case, area X has the highest temperature (22ºC), while areas Y and Z both have a lower temperature (18ºC). Therefore, air will move from area X to area Y or area Z.

However, since the responses to choose from indicate directionality in moving from lower temperatures to higher, the correct answer here is:

**area Y to area X**

Air moves from area Y (18ºC) to area X (22ºC).

The statement that best explains the temperature difference is:

**Warm air rises by convection to the upstairs.**

This is because warm air is less dense and tends to rise, resulting in a higher temperature upstairs compared to downstairs.

The option that is an example of heat transfer by conduction is:

**person getting warm from an electric blanket.**

Conduction is the transfer of heat through direct contact between materials. In this case, the heat from the electric blanket is transferred directly to the person's body through contact.
