Directions: A statement is given followed by two inferences I and II. You have to consider the statement to be true even if it seems to be at variance with commonly known facts. You have to decide which of the given inferences, if any, follow from the given statement.

Statement: Many students are addicted to mobile games and this leads to poor academic performance.

Inference:

I. Many Students are not paying attention to studies due to mobile games.

II. It is only because of mobile games that students fail in the examination. 

Explanation:

I. Many Students are not paying attention to studies due to mobile games: From the statement given, it can be inferred that many students' addiction to mobile games is affecting their academic performance negatively. This suggests that students are likely not paying enough attention to their studies because they are playing mobile games, so inference I follows.

II. It is only because of mobile games that students fail in the examination: However, the statement does not imply that mobile games are the only reason students fail in examinations. There could be multiple other factors contributing to a student's failure, such as lack of understanding, insufficient study, personal issues, health problems, etc. Therefore, inference II does not follow from the statement given.

Hence, the correct answer is option 4, i.e., only inference I follow.
