Why did the United States government want to obtain California?

Because America at the time, felt it was their right and duty to expand across the continent to to Pacific. The US wanted California for its great port cities along the Pacific, cities such as San Francisco and San Diego. James K. Polk also wanted to gain California from Mexico because he did not want the British to claim it.

Brainliest??

explanation:

there are two statements that are incorrect.

1. the marshall plan was a lend lease program. it was an economic plan that europe redevelop itself after wwii.

2. einstein didn't really do anything to further the allied cause in building the bomb. he merely sent a letter to fdr telling him (in 1939) that if the united states entered the war, perhaps it would be wise to build the bomb before germany did. i would say this answer is incorrect, but when america entered the war 2 years later, fdr thought it might be a good idea to take einstein's advice.

the 4th choice is definitely so wrong that is likely the single answer of this question

b.   jim crow laws were enacted in northern states.
