Answer:
It reduces strength.
Explanation:
It not desirable to produce concrete mixtures of a higher consistency than normal because the strength of the concrete decreases. Consistency plays an important role in the determination of strength of concrete. Less water than normal quantity in concrete increases the consistency but decreases strength due to incomplete chemical reaction while on the other hand, adding more water would increase water-cement ratio and reduces consistency as well as strength of the concrete so that's why necessary amount of water and cement should be added to get higher strength.
Society of the America and North Africa are closely parallel but their biggest difference is that Americans don't claim to be native and original people, thus one of the oddities of modern time is found in North Africa. American today classified themselves as a middle class.

Answer:
C.
Explanation:
Hi, fellow AP Human Geographer. Basically, all that arithmetic density means the total number of people per unit of land area. Having said that, we can immediately eliminate A. because increasing the population would only increase the total number of ppl. per unit of land area. Next, B. B can work, theoretically; however, there is a better answer. Next, D. D. says limiting the number of farmers; while this will technically reduce the number of ppl. per unit of land area, again there is a better answer. Next, E. I'd say this is the toughest choice; however, by increasing the area of urban areas, it can end up attracting more people instead. Overall, the best answer would be C., limiting the size of the population.
