The three decisions are in sequence and the conditions are all mutually exclusive (if any one is true the others must be false). Hence a test case that makes the first decision true will make the second and third decisions false and so on.
So test case 1 (say Time = 6) would exercise the path True, False, False, test case 2 (say Time = 15) would exercise the path False, True, False. Test case 3 would have to be Time = 12. This combination achieves 100 per cent decision coverage because each decision has been exercised through its true and its false outcomes.

Valid test objectives include finding defects (i), gaining confidence about the level of quality and providing information (ii), and preventing defects (iii). Debugging the code (iv) is not a valid test objective as it is a part of the development process rather than the testing process.
Reference: ISTQB CTFL Syllabus, version 4.0, lists the valid objectives of testing, which include finding defects, gaining confidence, and preventing defects.

For a review process to be successful, several factors must be in place. According to the ISTQB syllabus, successful reviews generally have clearly defined objectives (a), involve the right people who understand the objectives of the review (c), and place an emphasis on learning and process improvement (d). These elements ensure that the review is focused, effective, and contributes to the overall improvement of the software development process.
