1 . COVID-19 shutdowns forced people out of work and pushed tens of millions into poverty worldwide. Governments tried hard to provide aid. It was easy in a small country, but difficult for a country with large population and vast rural areas.     1     Doing a detailed, nationwide, house-to-house survey takes people time and money. Luckily, satellites can see poverty from space.

Researchers have been finding ways to identify areas of wealth and poverty in satellite images. Through some satellite data and aerial images of one town or another, you can sort of tell whether it’s wealthy or not. Wealthier homes tend to have metal roofs while poor homes tend to have thatched roofs. Wealthier neighborhoods have paved roads and bigger plots of lands, more spaced out.     2     The researchers trained artificial intelligence (AI) to recognize these patterns.

    3     The researchers put AI to work studying patterns of mobile phone use in those regions. Rich people will make just more phone calls than poor people. They also might make more expensive international calls. They might use more mobile data because they have smartphones.     4    

The researchers use the system to identify about 60,000 people to receive benefits. The advantage of the satellite imagery and phone data approach is that it’s extremely fast and very convenient.     5     In shocks like climate disasters where there’s no time or way to get detailed information on the ground, satellites mobile phones and AI could help deliver aid quickly to people in need.

A．It was opposite in a big country.

B．How do they locate the neediest people?

C．So there’s a lot of information in the images.

D．Most importantly, it’s very cheap to carry out.

E．Worse still, it’s not so economical as a house-to-house survey.

F．However, in general, poorer people will just have feature phones.

G．What the researchers did next was to target the neediest people in those regions.

2 . Many economists argue that Canada could have developed economically with little facilitation of the settlers. But in my opinion the settlers were vital in the country’s development of economy.

Settlers in Canadian history provided labour force that was apparently lacking in the country. Due to the thriving timber (木材) industry that led to the arrival of foreigners, the local population could barely satisfy the international demand for the demand. Emery and Kenneth claimed that the settlers who came to Canada as mere loggers had an impact in the development of the economy. Indeed, the settlers helped the production of more volumes of timber leading to increase in incomes for the government.

Settlers created considerable storage facilities for fishing. It is through these preservation technologies that the country was able to exploit its rich fish industry and increase its exports. Fishing technology improved greatly with many technologies of deep sea fishing. The technologies that came with the settlers increased the trading potential of the country, which in turn increase the incomes for government.

The success of settlers who ventured in agriculture ended into increased urge by locals and the government to invest in agriculture. In Ontario, settlers began planting such plants as corn, vegetables and reared dairy cattle. In the Prairies, the settlers also invested in grain growing with wheat being the most profitable crop.

Canadian settlers also led to changes in social and economic policies of the land. Due to increased immigration, land became a debatable issue where many people did not access land in a fair manner. The Canadian authorities came up with a wise land policy. Settlers could buy large amount of land cheaply and later resell the lands at a proper profit. This increased the ability of the country to increase its agricultural profits by having a superior land system.
