look at the people in images 2 and 4 and describe what they are doing. Are the situations formal or informal

Informal

Explanation:

The people in image 2 are not dressed up. They are wearing white T-shirts with cargo shorts. They also appear nervous or are being asked a question.

The people in image 4 seem to friends of some sort. They are exchanging hugs and are probably saying goodbye. This situation is also informal, as it is just a nice thing to do when saying bye to someone you know.

lack of land area is one of the things not mentioned that has contributed to the poor transportation and communication systems in nicaragua.
