This excerpt by British physician John Griscom was written in 1842. By providing the laboring classes with better tenements, improved ventilation, and healthy and cleanly arrangements in respect to yards, sinks and sewerage, they will certainly suffer less from sickness and premature mortality, and a vast amount of pauperism, crime, and wretchedness be prevented . . .

What is the most likely reason Griscom connected crime to poor living conditions?

People who were likely to die young did not worry about the consequences of criminal acts.
Living in unsanitary conditions often made people lose their sense of right and wrong.
Unhealthy people who could not earn a living were more likely to commit crimes.
Being a member of the laboring classes made people more prone to criminal behavior

Being a member of the laboring classes made people more prone to criminal behavior.

C- Unhealthy people who could not earn a living were more likely to commit crimes.

Explanation:

took the test

as university of miami psychologists debra lieberman and adam smith pointed out in a recent article in the journal current directions in psychological science, humans have social and psychological mechanisms to deter incest. with very few exceptions, marriages between brothers and sisters and between parents and their children are verboten in every human culture. the primary psychological anti-incest mechanism is the yuck response. even the idea of sex with their mom or dad, bro or sis is upsetting to most people. the psychologist jonathan haidt has found that nearly everyone is repelled by the prospect of brother-sister sex, even in hypothetical situations in which there is no chance of pregnancy).

the biological cost of incest

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.

answer; i believe the correct answer is (8) eight.
