I am not sure the answer

Code: Select all

/tmp/temp
├── documents

You are right. The answer is indeed illogical but after investigating I found out that the code snippet was actually supposed to be .contains("n") instead .contains(".txt"). The options and the explanations are written accordingly. Should be updated.

thank you for your feedback!
