A historian writes an essay on the effects of the Great Depression. He claims that the Depression mostly harmed
rural Americans and that people living in the cities
generally had no idea it was even happening.
A reader trying to determine whether the historian's interpretation is valid
would most likely:
O A. conduct research on the Great Depression to learn about the
factors that caused it.
B. determine whether the historian has written any other essays on
the Great Depression.
O C. write an argumentative essay suggesting that the historian does
not care about the poor.
O D. search for Depression-era primary sources from cities to see if
they mention urban poverty.

answer; i believe the correct answer is (anemia);

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
