The correct option is D.
The Mexico city was built on the ruins of an old lake. The lake was drained in order to provide the needed land for the city and water has to be regularly pump out of the underground aquifers in order to prevent flooding and also to provide drinking water for the city. This affected the supporting soil structure and result in the sinking of the city. The city has sunk by about 30 feet in the last 100 years and this has caused a lot of damages which are quite expensive to repair.
I don’t think so because there isn’t any evidence of the answer
Answer:
A letter is a written communication transmitted through a medium from one person (or group of people).
Explanation:
Dear jhon,
I write that letter to you and ask you for advice, because I can always count on you. This letter I'm passing through.
I have social anxiety symptoms and cannot say that I have this disease; but I feel great fear and discomfort as I perform the most simple social activity. Anybody at all, I don't know. I've got no friends apart from you. For more than six months I haven't left the house. When I came to go and meet the people, I was nervous, respiratory and trembling all across my mind. I stopped doing any kind of activity to avoid such sensations, including leaving my home.
I'm afraid I am living by myself all the time, but I can't see a future but total solitude, which causes me to cry out, to suffer hours and hours in advance.
But I wanted to speak with someone, so I have chosen you, I'm ashamed to speak.
I'm sorry, I hope you understood, and I miss you. I am sorry if it bothered you
your lovingly,
Aaron
