Correct Option (D)
: Neither 1 nor 2
Both assumptions 1 and 2 are invalid based on the information presented in the passage.
Incorrect Options:
-
Assumption 1: Development of agricultural technology is confined to developed countries.
The passage states that "Much of this change is brought about by affluent farmers in the West Americas." While this indicates a significant contribution from developed countries, the use of "much" does not imply that development is exclusively or entirely confined to these regions. The passage does not provide information to support the absolute confinement of agricultural technology development to developed countries.
-
Assumption 2: Agricultural technology is not adapted in developing countries.
The passage explicitly mentions, "Techniques developed in the West are being adapted in some places to make tropical crops more productive." This statement directly refutes the assumption that agricultural technology is not adapted in developing countries. Although the passage highlights the need for further extension of these practices to smallholders and subsistence farmers, it confirms that adaptation is already occurring in certain areas.
