Question in unclear..but I would say chemicals/hazards..?
A
Is do not no if this is correct
<span>Black codes were restrictive laws designed to limit the freedom of African Americans and ensure their availability as a cheap labor force after slavery was abolished during the Civil War. Though the Union victory had given some 4 million slaves their freedom, the question of freed blacks’ status in the postwar South was still very much unresolved. Under black codes, many states required blacks to sign yearly labor contracts; if they refused, they risked being arrested, fined and forced into unpaid labor. Outrage over black codes helped undermine support for President Andrew Johnson and the Republican Party.</span>
I believe it is A, but I wouldn't go by just my answer.
The correct answer to this open question is the following.
Although the question doesn't include options, we can say the following.
The "Diggers" were a group in the 1960s Haight-Ashbury neighborhood inspired by the original English Diggers and famous for promoting the anarchist guerrilla street theater.
These Diggers started in San Francisco Bay as a group of street theater that questioned the counterculture that surged in the 1960s with the hippies' ideals. Their performances in the streets of San Franciso were influenced by the bohemian art scene of the Bay Area and the peace movements that started in New York City. The group supported ideas of a free society where private property was no more. Instead, they favored the free exchange of things.
