The correct answer to this open question is the following.
Although there are no options provided, we can answer the following.
Studies have shown that capitalist countries have people living in poverty, and capitalist economies often have a great deal of inequality. If a writer is arguing that capitalism has more benefits than socialism, then this evidence functions as a counterclaim.
In this case, the writer had to give its arguments to rebut that affirmation. The counterclaim occurs when he tries to offset other claims. So after listening to the idea that capitalist countries have people living in poverty, and capitalist economies often have a great deal of inequality, the writer has to offer valid arguments and data to support its idea that capitalism has more benefits than socialism. It could be by numbers, statistics, references, and so on.
