Statement: The colour of blood is red due to the presence of red blood cells.
Conclusion I: If red blood cells are removed, blood will lose its red colour.
Conclusion II: Red blood cells will be red as long as they remain in the blood.
Analyzing Blood Colour Reasoning
The core of this problem lies in understanding the relationship between the statement and the given conclusions. We need to determine which conclusions are logically necessary consequences of the statement.
Statement Breakdown
The statement establishes a direct cause-and-effect relationship: The red colour of blood is attributed to the presence of red blood cells (RBCs).
Conclusion I Analysis
Conclusion I: If red blood cells are removed, blood will lose its red colour.
- The statement explicitly states that RBCs cause blood's red colour.
- Removing the cause (RBCs) should logically result in the absence of the effect (red colour).
- Therefore, this conclusion logically follows from the statement.
Conclusion II Analysis
Conclusion II: Red blood cells will be red as long as they remain in the blood.
- The statement explains why blood is red (because of RBCs).
- It does not provide information about whether RBCs inherently possess redness or if their colour depends on being inside the blood. RBCs contain hemoglobin, which is red, but the statement doesn't discuss the conditionality of this colour based on location.
- We cannot logically deduce from the given statement whether RBCs would change colour if removed from the blood or if their redness is solely dependent on being within the bloodstream.
- Therefore, this conclusion does not necessarily follow from the statement.
Final Determination
Based on the analysis, only Conclusion I is a logically sound deduction from the provided statement. Conclusion II makes an assumption about the properties of RBCs outside the context given in the statement.
Thus, only Conclusion I follows.
Important Questions from Statements and Conclusions
A situation is given, followed by two conclusions I and II. Read the situation and both the conclusions carefully and select the correct answer.
Situation:
Since the past 15 years, 75% of the products in the world’s pottery market comes from Country K. However, the employment in the pottery industry of Country K has been consistently declining by 5-9% every year since the past 3 years.
