How were kennedy and johnson similar?
they both took office after the assassination of a president.
they both lowered the minimum wage for workers.
they both supported social legislation to improve the us.
© they both opposed civil rights legislation.

The right answer is " They both supported social legislation to improve the US."

Explanation:

President John F. Kennedy supported the same rights cause for all people in the U.S., though in office he was cautious due to his narrow victory and small working margins in Congress. He appointed many African-American public officers. On his side, President Lyndon B. Johnson signed the Civil Rights Acts in 1964.

no statements but ok.

the statement that best describes the idea of manifest destiny that was used in the 19th century would be that "it was fate that the united states would continue to  expand westward," since people thought the us was "destined" to do so.
