Anyone know the answer ? , thank you

The answer is C. 253.

Explanation:

The bold lines indicate increases in elevation and are labeled in 50 meter increments. The X starts at 50 meters up the hill. To get to 300 meters, it is 250. Plus the extra 3 meters to get to the very top that is labeled as 303 meters. So you would add 250+3 to get 253.

the dust bowl, otherwise known as the dirty thirties, was a huge dust storm that killed multiple (and i mean  multiple) farmer's crops, leaving them homeless, and foodless, and jobless. in california, there were 5.7 million residents, and the population shrank as mexicans were repatriated. however, when the dustbowl happened, a lot of people began to move to california. by 1940, 250,000 people had arrived. therefore, your answer would be  the population increased, massively.  i hope this !
