A and D leads to unemployment:
Option A:
Government restricts export of unprocessed cashew nuts.
1. The restriction limits the number of farmers who can profitably grow cashews.
2. Many small cashew farmers are driven off their land due to lack of profitability.
3. These farmers move to the cities, increasing the population seeking urban jobs.
4. The increase in job seekers potentially raises urban unemployment rate.
Option D:
1. The income earned by workers in the processing plants is generally greater than that earned by agricultural laborers in rural areas.
2. This wage disparity could potentially attract more people to the cities for higher wages.
3. This migration to cities might increase the number of job seekers in urban areas.
4. The increase in job seekers could potentially raise the urban unemployment rate.
As you can see, both options might potentially lead to an increase in urban unemployment. However, Option A directly ties this outcome to the government's policy on cashew exports, whereas Option D describes a general scenario that might be true irrespective of the specific government policy in question. Therefore, Option A is the better choice to complete the argument.
