💡 Analysis & Explanation

Venn Diagram Mapping ▼

Statement 1 entirely places the circle for 'chairs' inside the larger circle for 'tables'. Statement 2 draws a distinct, separate circle for 'desk' that has absolutely no intersection with the 'tables' circle.

Analyzing Conclusion I ▼

Since 'chairs' are completely locked inside 'tables', and 'tables' are entirely restricted from touching 'desk', it is a logical impossibility for any 'chair' to be a 'desk'. Thus, Conclusion I is demonstrably true.

Analyzing Conclusion II ▼

The circle of 'tables' encompasses the smaller circle of 'chairs'. This visually and logically means that at least that specific overlapping portion of 'tables' must also be 'chairs'. Therefore, Conclusion II is also true.

Conclusion ▼

Based on deductive logic, both conclusions I and II unequivocally follow.
