What this topic is asking
Topic 9.1 covers the technological advances that accelerated globalization after 1900. It asks you to explain the breakthroughs in communication, transportation, energy, and medicine that shrank the world and intensified the exchange of goods, money, people, and ideas across borders, turning the planet into a single connected system.
What "advances in technology and exchange" means
The communication revolution
Information became instant and global.
The transportation revolution
Moving goods and people got faster and cheaper.
- Air travel. Jet aircraft move people across the world in hours, enabling global business, tourism, and migration.
- Container shipping. The standardized shipping container slashed the cost and time of moving goods by sea, making global supply chains and cheap international trade possible.
- Integrated markets. Together, fast and cheap transport let goods be made in one part of the world and sold in another, integrating the global economy (Topic 9.5).
Energy, medicine, and agriculture
Other technologies sustained the connected world.
- Energy. Abundant oil, large-scale electricity, and nuclear power supplied the energy that this connected, industrialized world demanded.
- Medicine. Vaccines, antibiotics, and new treatments dramatically reduced disease and extended life expectancy, contributing to population growth (Topic 9.3).
- Agriculture. The Green Revolution introduced high-yield crops, fertilizers, and irrigation that vastly increased food production, feeding a booming global population.
These advances raised living standards for many, though their benefits were unevenly shared, a tension Topic 9.2 explores.

A Long Essay Question (LEQ), scored on the 6-point causation rubric.
Thesis (1): "The most significant technological cause of globalization was the revolution in communication, from the telephone and radio to the internet, because it allowed near-instant global exchange of information and money, though transportation advances like container shipping and air travel were also essential."
Contextualization (1): situate the advances in the long history of shrinking distance through technology.
Evidence (2): communication from radio to the internet; air travel and container shipping; new energy and medical technologies.
Analysis (2): explain HOW communication technology made instant global exchange possible, then add complexity by weighing it against the transport advances that moved goods and people."
