Which scientific advancement is linked to the muslim scholar al-
khwarizmi?
o a. he discovered new species of life on the ocean floor.
b. he developed a unified theory of quantum mechanics.
c. he transformed the field of particle physics.
d. he invented a new branch of mathematics, algebra

The correct answer is:

D. He invented a new branch of mathematics, algebra.

Explanation:

Al-Khwarizmi was a Muslim mathematician, astronomer and geographer, that is also known as the Father of Algebra, because he was the first to introduce letters to equations, as a sign of an unknown number to solve equations, and to treat Algebra as an independent science.

Al-Khwarizmi demonstrated the method to solve quadratic equations and proved the methods of reduction, known in Arab as Al-Jabr (the transposition of negative quantities to the other side of the equation to transform them into positive quantities) and balancing, known in Arab as Al-Muqâbalah (the elimination of identical quantities of both sides of the equation).

here are some major conflicts i found. maybe pick one and do more research on it. (cause i ain't writing 6 paragraphs)

in 1877, the nez perce war took place.

1881 - president james garfield was assassinated.

1882 - the chinese exclusion act was passed.

1883 - a decision in the civil rights cases legalized racial segregation in the united states.

1887 - the dawes act was passed.

1893 - the panic of 1893 took place. (what a creative name)

and there are probably other topics you can find if you just search up "united states timeline," or "conflicts in the 19th century for america."

then once you find a topic you like find out how it affected the people of america and what not. (sorry if this feels a bit short changed, history was and never will be one of my strong topics)
