A transparent square sheet shown above is folded along the dotted line. The folded sheet will look like \(\underline{\hspace{2cm}}\)


Step 1: Identify the line of folding.
The dotted vertical line represents the axis of folding. Since the sheet is transparent, all markings on one side of the fold will appear mirrored on the other side after folding.
Step 2: Analyze the curve and markings.
The curved shape and the small angular markings on the right side of the dotted line will reflect symmetrically to the left side when folded. The relative orientation of these markings must be reversed horizontally.
Step 3: Compare with given options.
Option (B) correctly shows:
\[\begin{array}{rl} \bullet & \text{the mirrored curvature,} \\ \bullet & \text{correct alignment of the angular markings,} \\ \bullet & \text{proper overlap produced by transparent folding.} \\ \end{array}\]
Options (A), (C), and (D) either misplace the mirrored curve or incorrectly orient the internal markings.
Step 4: Conclusion.
Therefore, the folded transparent sheet will look like option (B).

In the diagram, the lines QR and ST are parallel to each other. The shortest distance between these two lines is half the shortest distance between the point P and the line QR. What is the ratio of the area of the triangle PST to the area of the trapezium SQRT?
Note: The figure shown is representative

Consider the relationships among P, Q, R, S, and T:
• P is the brother of Q.
• S is the daughter of Q.
• T is the sister of S.
• R is the mother of Q.
The following statements are made based on the relationships given above.
(1) R is the grandmother of S.
(2) P is the uncle of S and T.
(3) R has only one son.
(4) Q has only one daughter.
Which one of the following options is correct?
