Landlocked countries, regions with diseases that are difficult to control or cure, and areas that are very far from major markets for their goods are all at a developmental disadvantage, and this disadvantage was probably greater in an earlier era, when medical knowledge was limited and transportation and communication costs were much higher. By virtue of weather and disease, tropical environments in particular may be less conducive to urbanization and industrialization than temperate zones.
Some scholars ascribe a substantial portion of the developmental problems of tropical regions like sub-Saharan Africa to geography itself. But geographic factors cannot be the whole story, as there is a great deal of variation among countries within the same regions.
If we compare less developed countries that have very similar geographic characteristics, we find that some have done extremely well, while others have done very poorly. While the climate and geography of a nation shape its development, they do so through their impact on the people, social structures, politics, and policies of the nation.
Given below are two statements, one labelled as Assertion A and the other as Reason R. In the light of the above statements, choose the most appropriate answer from the options given below.
The answer is that both A and R are correct and R correctly explains A.
Being landlocked adds cost to moving goods to distant markets.
In earlier times this disadvantage was far greater, so Assertion A is correct.
The passage says transportation and communication costs were then much higher.
Higher such costs are exactly why the disadvantage was greater, so Reason R is correct and explanatory.
So R is the correct explanation of A.
So the answer is that both are correct and R explains A.
