Practice Reading: Multiple Choice, Single Answer ID: #46516 The cultivation
Instructions ›
Read the text and answer the multiple-choice question by selecting the correct response. Only one response is correct.
Four specific activities have been identified as major contributors to the desertification pro cess: overcultivation, overgrazing, firewood gathering, and overirrigation. The cultivation of crops has expanded into progressively drier regions as population densities have grown. These regions are especially likely to have periods of severe dryness, so that crop failures are common. Since the raising of most crops necessitates the prior removal of the natural vegetation, crop failures leave extensive tracts of land devoid of a plant cover and susceptible to wind and water erosion.

Option 3: "Removal of the original vegetation"

Explanation: The text explicitly states that raising most crops requires the removal of natural vegetation. This is a direct connection to the process of raising crops, as it highlights the environmental impact of agricultural practices.

Option 1: "Lack of proper irrigation techniques"

Explanation: The text does not mention anything about improper irrigation techniques being associated with raising crops. Instead, it discusses overirrigation as a contributor to desertification, which implies that irrigation is being used, albeit excessively.

Option 2: "Failure to plant crops suited to the particular area"

Explanation: The text does not address the suitability of crops for specific areas. It focuses on the removal of natural vegetation and the consequences of crop failures, rather than the failure to plant appropriate crops.

Option 4: "Excessive use of dried animal waste"

Explanation: The text does not mention the use of dried animal waste in relation to raising crops. Instead, it focuses on the activities that contribute to desertification, which do not include this option.
