The correct answer is B) a random sample.

The election of 1936 demonstrated that a good poll needed which of the following a random sample.

The election of 1936 was held during the tough years of the Great Depression. In the election participated Democratic candidate Franklin D.Roosevelt and Republican candidate Alf Landon. Roosevelt won by large numbers in the electoral vote: 523-8. These results taught pollers that good polls needed a random sample to get better indicators.
