The Steam Engine

Reasoning:

The plow was used to allow the plowing of fields to produce agricultural, it was an ends to a means; a tool.

The Steam engine was also just like that; It was a tool. The steam engine allowed us to import/export things from long distances, build new technologies with steam engine manufacturing.

Both technologies greatly helped push the human race to the next age.

Breaking down the choices:

The domestication of plants and animals happened long before the industrial age, even before the creation of the U.S.A! So this answer is wrong.

The computer chip is a creation of the "Information age", an age that is newer than the industrial age. So this answer is wrong.

The unmapping of the DNA molecule is also incorrect.

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.
