Concept:
- In "which combination of statements is valid" questions, every statement can be checked against the passage one by one, but the answer choices themselves can be used to eliminate statements that conflict with the passage, often reaching the answer faster.
- A statement can only be used to persuade Ajay toward Language A if it does not contradict a fact already given in the passage; a statement that argues the opposite of a stated fact is invalid no matter how reasonable it sounds by itself.
Step 1: Test statement IV against the passage.
The passage states Language B "has the potential to provide numerous professional advantages in the future." Statement IV claims Language B "may not offer as many career opportunities," which goes against this stated fact, so IV is invalid. The only option containing IV is "II and IV," so that option is eliminated.
Step 2: Test statement I.
Ajay is learning the language "as a hobby," and the passage never says he needs it for career reasons, so pointing out that his purpose is purely recreational is consistent with the passage and gives him a real reason to prefer the easier language. I is valid.
Step 3: Test statement II.
The passage already calls Language B "more challenging to master." A statistic showing only one-third of learners clear the elementary test, with Ajay likely to struggle too, is consistent with this and gives Ajay a direct practical reason to avoid Language B. II is valid.
Step 4: Test statement III.
The passage already states Language A "is easy to learn, and even his sibling speaks it." III simply restates this as a reason it will be easier for him, which is fully consistent with the passage. III is valid.
Step 5: Combine the surviving valid statements.
I, II and III are each individually valid, and only the option listing all three of them together remains among the answer choices.
Final Answer: I, II, and III (Option E)
