Statement 1 is correct: More than 90% of the world's population lives in the Northern Hemisphere. Statement 2 is incorrect: The most populated zone of the world is 200N to 400N, where more than 50% of the world's population lives.

Both the statements are true, but R is not the correct explanation of A. In fact, it is the well qualified and innovative man power of Japan that led to its industrial success. No doubt, Japan imports a huge chunk of most of the mineral resources it needs for its industrialisation.

Intensive farming aims at maximum possible production on the limited farms with all efforts possible under the circumstances. Its characteristics are: (i) Intensive farming is capable of raising more than one crop a year. (ii) Huge capital and human labour is employed on every hectare of land. (iii) It is practiced in most parts of densely populated areas. (iv) Low level of technology, if any, is involved in such type of farming.

Both the statements given are true, but R is not the correct explanation of A. In fact, A explains the reason behind R. Newspaper circulation in Sri Lanka is high because of its high adult literacy.

Veddas are indigenous people of Sri Lanka, an island country in the Indian Ocean.

Both the statements are true and R is the correct explanation of A. Chile is endowed with the world's largest deposits of porphyry copper and this leads to largest production of copper in Chile.

The factors that influence patterns of settlement are:

Economic and Human Influences Generally, the promise of material reward is the most important factor in human settlement. In this case, the interest in gaining more profit in proportion to labor exerted is central in dictating settlement patterns. These are necessary, but not sufficient causes of settlement. Parts of this variable include the promise of employment and a stable economy.

Physical Influences The physical environment is next in importance. In agricultural settlement, the nature of the soil and access to both water and transport are essential ingredients in making sense out of settlement patterns. But even further, things such as the safety and stability of the existing settlement is equally important. Besides, the existing density of population, if high, leads to dispersal of population.

Technological Influences A more specific consideration is the existence of well-established patterns of communication, transportation and markets, which are all central to this variable. To some extent, it is connected to the physical environment, as the technological makeup of the existing settlement exists as an adaptation to the nature of the topography and the availability of resources.

Historical Influences Ethnic compatibility, speaking the same language and the basic cultural forms of co-existence cannot be left out of this discussion. The historic nature of settlement speaks to the specific language and cultural norms that make up a society, making it easier for one that shares these to fit in, and discouraging strangers. This not only makes it easy for similar settlers to fit in, but also makes the community more and more cohesive. Fear of foreign invasions to an area leads to migration to safe places.

Statement 1 is correct: Tokyo (Japan), Seoul (South Korea), Beijing (China), Jakarta (Indonesia) and Mumbai (India) - all of which lie in Asia - are among the ten largest metropolitan cities of the world.
