Answer;

B. Urban dwelling provides better access to goods, services, and jobs.

Explanation;

The urban migration was caused by the increase of jobs in cities during the industrial revolution and the improved access to goods and services that came with changes in transportation.

Generally, people migrate from rural to urban areas for economic/employment opportunities, but the specific reasons can be categorized as either "push" or "pull" factors. Push factors include what makes the people move away from a place; for instance, a lack of jobs or social opportunities. Pull factors, on the other hand, are why people want to come to a place, for reasons such as better job opportunities or easier access to amenities, including education and healthcare.

Urban dwelling provides better access to goods, services, and jobs.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
