Hi and 1.Is To make sure the reader knows that simply reading the steps is not enough and 2. Is china has very busy streets; Chinese people don't have good manners. hope I helped
The usage of at is the error
Explanation:
IN is for large spaces that can enclose (village, city, state, province, country, continent, mountain range, desert, zone, etc.)
ON is for surfaces.( street/avenue/road, most bodies of water, etc)
AT is for points ( We live at an address, at a certain point and at a certain person’s residence if just the possessive case is used to mean the residence.)
Examples:
1- I live in Belgrade.
2-They live on Mulberry Street
3-I live at 199 Main Street
Conclusion: AT is a tiny point, ON is bigger, and IN is big enough to surround you.
Hey There!
Here is your answer:
Your answer is "During the 1930s, extreme drought and high winds made life incredibly difficult in the Great Plains region of the United States."
Is sentence tells that during the 1930s there were extreme droughts which made life difficult then it goes on about facts about the drought and what happened!
Hope this helps!
