Step 1: Analyze Statement I.
Statement I states a fact: there is a significant increase in unemployment among the youth. This is a general socio-economic condition.
Step 2: Analyze Statement II.
Statement II describes a specific event: a large number of highly qualified individuals are applying for a relatively low-level job (clerk).
Step 3: Determine the relationship between the two statements.
The condition described in Statement I (high unemployment) provides a direct and logical reason for the event in Statement II. When jobs are scarce (high unemployment), people, including those who are overqualified, are more likely to apply for any available position, even if it is below their qualification level. Therefore, the increase in unemployment is the cause, and the flood of applications from highly educated candidates is the effect.
