Question 2

About how many people lived in the eight countries of South Asia in 2025, according to the World Bank?

Question 3

Which body of water receives the combined flow of the Ganga and the Brahmaputra?

  1. The Bay of Bengal
  2. The Arabian Sea
  3. The Red Sea
  4. The Caspian Sea
Show Answer

The correct answer is A. The Ganga (Padma) and the Brahmaputra (Jamuna) join in Bangladesh, flow with the Meghna, and empty into the Bay of Bengal through the world's largest delta. The Arabian Sea is where the Indus ends, on the other side of the subcontinent.

Question 4

What is the best explanation of the difference between "South Asia" and the "Indian subcontinent"?

  1. They are two names for the country of India.
  2. South Asia is only the island countries, while the subcontinent is the mainland.
  3. South Asia is a group of eight countries; the subcontinent is a physical landmass south of the Himalaya.
  4. The subcontinent includes Afghanistan, but South Asia does not.
Show Answer

The correct answer is C. "South Asia" names a region made up of eight countries, while "Indian subcontinent" is a geographic term for the landmass on its own tectonic plate. Option D has it backward: Afghanistan is usually counted in South Asia but not in the subcontinent.

Question 5

Why does the summer monsoon blow from the southwest toward South Asia?

  1. The Himalaya pushes air south in summer.
  2. The land heats up faster than the Indian Ocean, so moist ocean air flows in toward the warm land.
  3. The ocean is hotter than the land in summer, so air flows out to sea.
  4. Winds from Central Asia carry rain over the mountains.
Show Answer

The correct answer is B. In early summer the land warms faster than the ocean, air rises over the land, and cooler, moist air from the Indian Ocean flows in from the southwest, bringing rain. Option C reverses the pattern, which is closer to what happens in winter.

Question 6

Why is the Indo-Gangetic Plain one of the most densely populated places on Earth?

  1. Its rivers spread fertile alluvium, and water from Himalayan rivers supports large-scale farming.
  2. It is the highest and coolest part of the region.
  3. It is a desert with large oil reserves.
  4. It is an island chain with many ports.
Show Answer

The correct answer is A. The Indus, Ganga and Brahmaputra built the plain from river soil, and their water makes intense farming possible, which supports huge populations. Option B describes the Himalaya, not the plain.

Question 7

Ayesha's family is from Lahore, Pakistan, and Nima's family is from Solukhumbu, Nepal. Ben says, "So they both live near the Himalaya, which is in Nepal." Which response best corrects Ben?

  1. "The Himalaya is only in India."
  2. "Lahore is on the Deccan Plateau, far from any mountains."
  3. "Nepal has no mountains; they're all in Pakistan."
  4. "The Himalaya stretches across five countries, including Pakistan, India, Nepal, Bhutan and China, so it isn't in just one country."
Show Answer

The correct answer is D. The Himalaya spans Pakistan, India, Nepal, Bhutan and China, about 2,400 km in all. Option B is wrong because Lahore is on the Indo-Gangetic Plain in Punjab, and the Deccan Plateau is in central and southern India.

Question 8

Zara's cousin in Dhaka is planning a June trip to visit family in India and asks Zara when the rains start there. Using the chapter, where does the southwest monsoon normally arrive on mainland India first, and around what date?

  1. Delhi, around 1 May
  2. Kerala, around 1 June
  3. Kabul, around 1 July
  4. The Thar Desert, around 15 June
Show Answer

The correct answer is B. The India Meteorological Department's normal onset date over Kerala, at India's southwest tip, is around 1 June. The monsoon then covers all of India around 8 July. Kabul is wrong because Afghanistan lies mostly outside the monsoon zone.

Question 9

The Deccan Plateau is drier than the Kerala coast, even though both are in southern India. What is the best explanation?

  1. The Deccan is closer to the Thar Desert.
  2. The Eastern Ghats block all rain from the Bay of Bengal.
  3. The Western Ghats catch the monsoon winds from the Arabian Sea, so much of the rain falls on the coast side before the air reaches the plateau.
  4. The Deccan is at sea level, and rain only falls on mountains.
Show Answer

The correct answer is C. Monsoon winds rise over the Western Ghats and drop much of their rain on the western slopes and coast, leaving the plateau behind them drier. Option B can look right, but the Eastern Ghats are low and broken, so they affect the weather much less.

Question 10

A club member finds a website that lists South Asia's population as about 1.69 billion for 2025, not 1.99 billion. What is the most likely reason for the difference?

  1. The website is counting a different set of countries; the World Bank's own "South Asia" group now leaves out Afghanistan and Pakistan.
  2. The population of South Asia fell by 300 million people in one year.
  3. The website forgot to count India.
  4. The smaller number counts only people who speak Hindi.
Show Answer

The correct answer is A. Since mid-2025 the World Bank groups Afghanistan and Pakistan with the Middle East and North Africa, so its "South Asia" total covers only six countries. Leaving out India (option C) would make the number far smaller, about 0.5 billion.
