Statement — Declaration of strike by teachers at the time of paper evaluation has become an incurable disease and a great threat to the government.\n\nConclusions —\nI. Paper evaluation is the most important duty of teachers.\nII. Teachers are always in search of an opportunity to get their demands fulfilled.

Introduction / Context:
The statement notes a pattern: strikes are declared specifically at evaluation time, causing systemic risk. We test whether evaluation is “most important” (I) and whether teachers opportunistically press demands (II).

Concept / Approach:
I is too strong; “most important” is not stated. Teaching, mentoring, and other duties may be equally or more central. II follows: selecting a high-leverage time (evaluation) repeatedly indicates strategic timing to push demands.

Final Answer:
Only conclusion II follows.
