SAT English Practice Question

The passage describes how a certain type of research, namely, behavioral economics, challenges traditional economic theory. It's given that the study of behavioral economics focuses on the ways in which people make decisions and how those decisions may deviate from those predicted by traditional economic theory. For example, the study of behavioral economics has shown that people may be more influenced by social factors, such as emotions and personal experiences, than by rational considerations. This leads researchers to conclude that traditional economic theory, based on the assumption of rational actors, may not be adequate for explaining all economic decisions and behaviors. What is the most likely reason why the writer uses the phrase "for example"?

1. A.illustrate the key characteristics of traditional economic theory.
2. B.provide a specific example that supports a claim about behavioral economics.
3. C.introduce a distinction between behavioral economics and traditional economic theory.
4. D.compare the approaches used in behavioral economics and traditional economics.
