Explanation: To find the number of unemployed in June of that year, we need some equation to translate a percent to a number. Statement (1) is sufficient: 8.4 percent of the labor force was unemployed in May, a percent equal to 3.36 million. From there, you can find the total size of the labor force, which is the same as it is in June. Statement (2) is also sufficient: the difference between the percent of unemployed men in June and the number in May was 0.3% of the labor force, a percent equal to 120,000. From there, you can find the total size of the labor force. Choice (D) is correct.
