Answer:
Giving that: The following is a sequence of undo-log records written by 2 transactions T and U:
< START T >;
< T,A,10 >;
< START U >;
< U, B, 20 >;
< T, C, 30 >;
< U, D, 40 >;
< Commit U >;
< T, E, 50 >;
< Commit T >;
1. < START U >
Recovery action in this case will be undo(-1) and undo(0). All restored to its original Value
log records < T, A, 10 >, < T, abort >; as written out
2. < T, E, 50 >
Recovery action in this case will be undo(8) and redo(0). A and C is restored to its original value, B and D are set to 20 and 40
log records <T, C, 30 >, < T, A, 10 >, < T, abort > are written out
3. < Commit T >
Recovery action in this case will be redo(7) and redo(4). A and C are set to 10 and 30, B and D are set to 20 and 40

Reason:
The wood that we choose should be perfect and should give long-life to use the instrument.
2. If we consider about strings, then I would suggest that the material that you choose should be "ductile and hard".
Reason:
Thin wires can be drawn.
3. In case of Brass, it should be "malleable metal", so that the outcome of the instrument will satisfy the need.
XLS would be it, avi contains like sounds and stuff
