Migration

Loss of investment in education and shortage of skilled professionals

Step 1: The scenario describes educated professionals (doctors and engineers) leaving their home country — this is the definition of brain drain. Step 2: The most direct negative impact for the home country is that the government spent money training these people (investment in education), but instead of benefiting the home country, those professionals now serve another country. Step 3: The textbook explicitly lists 'loss of investment in higher education' and 'shortage of skilled and competent people' as key negative impacts of brain drain on India. Step 4: Option A is wrong — when people emi

Economic depression in rural areas of northern Europe pushed people to migrate, and the US needed workers to open up the continent

Step 1: The textbook states that during the 19th and 20th centuries, migration from Europe brought about 41 million people to North America. Step 2: The main reason behind it was the 'economic depression in the rural areas of northern Europe' — this is a push factor (poverty and lack of jobs in Europe). Step 3: At the same time, the US needed people because 'the whole continent was to be opened up' — this is a pull factor (opportunity and need for workers in America). Step 4: It was not forced by the US government — it was voluntary migration driven by economic conditions. Step 5: While some E

It widens income inequality because families receiving large remittances become richer while others do not

Step 1: When working-age people migrate to cities or abroad, they earn money and send remittances (money transfers) back home to their families. Step 2: However, not every family in the village has migrants sending money. Only some families receive large remittances. Step 3: Families receiving large remittances invest in their farms, buy more land, and improve productivity — making them progressively richer. Step 4: Families without migrant members do not receive remittances and cannot make these improvements, so they stay at the same economic level or fall behind. Step 5: The textbook explici

Australia is underpopulated and faces a shortage of certain categories of skilled workers

Step 1: The textbook provides a direct statement about Australia: it is 'underpopulated and short of certain categories of skilled workers.' Step 2: Being underpopulated means Australia has a very large land area but relatively few people, so it actively needs more people to develop and manage the country. Step 3: The shortage of skilled workers means Australia needs professionals from other countries to fill important roles in its economy. Step 4: Option A is the complete opposite — Australia is underpopulated, not overpopulated. Option C is incorrect because economic reasons (skilled workers
