This question is slightly easier than the earlier one. Let's see the critical elements of the passage. The most important critical element is "forensic phonetics in movies and television", and "these have led to errors in real-life justice, with unrealistic expectations of the capabilities of forensic science". 1 goes out because it misses the context of "movies and television". 3 is a complete distortion, whereas 4 misses the "unrealistic expectations" part. 2 is the best choice in every way.
