(ii) The throws in the last round by both Jakub Vadlejch and Vitezlav Vesely were fouls and were not considered for scoring.
(iii) After four rounds, Vitezlav Vesely was in the second position and could not improve upon his best throw in the succeeding rounds.
(iv) In the fourth round, the throw by Jakub Vadlejch was the best in that round.

Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Build a simple round by round elimination table for Vitezlav Vesely instead of eliminating clue by clue in prose.
List the six rounds as columns: R1, R2, R3, R4, R5, R6, and mark each one Possible or Not Possible as the clues are read.
Step 2: Mark R1 and R2.
Clue (i) explicitly excludes Vitezlav (one of the other two athletes besides Neeraj) from having a medal winning throw in rounds 1 and 2. Mark R1 = Not Possible, R2 = Not Possible.
Step 3: Mark R6.
Clue (ii) says Vitezlav's round 6 throw was a foul, so it could not have been counted as his best. Mark R6 = Not Possible.
Step 4: Mark R5.
Clue (iii) says Vitezlav's position and best throw were already fixed by the end of round 4 and did not change afterward, meaning nothing in round 5 (or 6) could be his best. Mark R5 = Not Possible.
Step 5: Mark R4.
Clue (iv) attributes the best throw of round 4 to Jakub Vadlejch specifically, distinguishing round 4 as Jakub's standout round rather than Vitezlav's. Mark R4 = Not Possible.
Step 6: Read off the surviving column.
Table state: R1 Not Possible, R2 Not Possible, R3 Possible (untouched by any clue), R4 Not Possible, R5 Not Possible, R6 Not Possible. Only R3 remains marked Possible.
Step 7: Conclude.
Vitezlav Vesely's best throw must have occurred in the third round, the only round not excluded by any of the four given observations.
\[ \boxed{\text{Third}} \]

A database has 25,000 fixed-length records of 100 bytes (primary key 15 bytes). The data file is block-aligned so each record is fully contained within a block. The file is indexed by a primary index file, also block-aligned and ordered. Block size is 1024 bytes and a block pointer is 5 bytes. Each index entry stores the block’s anchor key (15 bytes) and a pointer (5 bytes). Binary search on an index file of \(b\) blocks needs \(\lceil \log_2 b \rceil\) block accesses in the worst case. Given a key, the number of block accesses required to identify the data file block that may contain the record, in the worst case, is ____________.
