Problem: Eritrea:

Additionally, the Italian Eritrea administration opened a number of new factories, which produced buttons, cooking oil, pasta, construction materials, packing meat, tobacco, hide and other household commodities. In 1939, there were around 2,198 factories and most of the employees were Eritrean citizens. The establishment of industries also made an increase in the number of both Italians and Eritreans residing in the cities. The number of Italians residing in the territory increased from 4,600 to 75,000 in five years; and with the involvement of Eritreans in the industries, trade and fruit plantation was expanded across the nation, while some of the plantations were owned by Eritreans.

Besides Eritreans, which other nationality increased its city population because of new industries?

Problem: Madonna (entertainer):

Madonna's emergence occurred during the advent of MTV; Chris Nelson from The New York Times spoke of pop artists like Madonna saying, "MTV, with its almost exclusively lip-synched videos, ushered in an era in which average music fans might happily spend hours a day, every day, watching singers just mouth the words." The symbiotic relationship between the music video and lip-syncing led to a desire for the spectacle and imagery of the music video to be transferred to live stage shows. He added, "Artists like Madonna and Janet Jackson set new standards for showmanship, with concerts that included not only elaborate costumes and precision-timed pyrotechnics but also highly athletic dancing. These effects came at the expense of live singing." Thor Christensen of The Dallas Morning News commented that while Madonna earned a reputation for lip-syncing during her 1990 Blond Ambition World Tour, she has subsequently reorganized her performances by "stay[ing] mostly still during her toughest singing parts and [leaves] the dance routines to her backup troupe ... [r]ather than try to croon and dance up a storm at the same time."

What came as an expense of live singing?
---
A: highly athletic dancing

It became widely adopted, particularly in North America and Europe starting in the 1970s as a result of the 1970s energy crisis.
