Analysis of Statements
To understand why option 'B' is the correct conclusion, let's break down the provided statements:
1. Membership Requirement
- Only those who have a pair of binoculars can become members of the birdwatchers club.
- This implies that possessing binoculars is a necessary condition for membership.
2. Possession of Cameras
- Some members of the birdwatchers club have cameras.
- This indicates that not all members might have cameras, but at least some do.
3. Participation in Photo Contests
- Members who have cameras can take part in photo-contests.
- This shows that camera ownership among members allows participation in contests.
Conclusion Evaluation
Now, let's evaluate the conclusions based on the statements:
- Option A: All those who have a pair of binoculars are members of the birdwatchers club.
- This is incorrect because the statements do not specify that all binoculars owners are club members.
- Option B: All members of the birdwatchers club have a pair of binoculars.
- This is correct as the first statement states that only those with binoculars can be members. Thus, all members must indeed possess binoculars.
- Option C: All those who take part in photo-contests are members of the birdwatchers club.
- This is not necessarily true; the statements do not confirm that all contest participants are members.
- Option D: No conclusion can be drawn.
- This is incorrect since we can definitively conclude that all members have binoculars.
Final Conclusion
The logical analysis leads us to conclude that option 'B' is indeed the correct answer, as it follows directly from the membership requirement stated in the first statement.
