Pretty sure it's basically saying to answer it for yourself and 3 other people. So for the tongue roll, on self, if you can roll your tongue say yes, for subject 1, ask another person, if they can say yes, if subject 2 (another person) can't, say no, and so on.

Drag each label to the correct location. Each label can be used more than once.
sertanlavr [38]

Answer:

There are 4 types of breezes: land breeze, sea breeze, mountain breeze and valley breeze.

The breeze will originate from an area of high pressure and travel towards/blow in the direction of the area at a lower pressure.

In each case, the name of the breeze indicates where the breeze is blowing from. For instance, the land breeze will blow from the land (at high pressure) to the sea (at lower pressure). A mountain breeze will blow from mountain (at high pressure) towards the valley (at low pressure).

Hope that answers the question, have a great day!
