A volunteer who sends packages to hospital patients is preparing three packages containing exactly five items each from a supply of eighteen available items-four games, six jigsaw puzzles, and eight novels. The packages must conform to the following.
conditions:
The three packages together contain all of the novels. Each package contains at least one jigsaw puzzle. No package contains more games than novels.
Step 1: Each package must have 5 items. Options (A) and (D) have the wrong total (A = 5 but only puzzles, which violates ""at least one novel""; D = 6 items).
Step 2: Check condition “No package contains more games than novels.”
- (B) 1G, 4N → Games (1) ≤ Novels (4) ✅, and contains ≥1 puzzle? ❌ (fails, no puzzle).
- (C) 1P, 4N → Games = 0, Novels = 4 ✅, contains ≥1 puzzle ✅. This works.
- (E) 3G, 1P, 1N → Games (3)>Novels (1) ❌.
Answer: The only valid package is (C).
\[ \boxed{\text{One jigsaw puzzle, four novels}} \]
Step 1: Total games available = 4. If first two packages use 2 games each, all 4 games are used. So third package cannot have any games.
Step 2: Third package must have 5 items (no games). So only puzzles and novels. It must have ≥1 puzzle.
Step 3: Options check:
- (A) 1P + 4N = 5 ✅ possible.
- (B) 2P + 3N = 5 ✅ possible.
- (C) 4P + 1N = 5 ✅ possible.
- (D) includes 1G ❌ impossible (all games already used).
- (E) includes 2G ❌ impossible.
Step 4: Must ensure all novels = 8 across 3 packages. If first two had 4 games already, they each also must have puzzles and novels. The only consistent third package is (B) 2P, 3N.
\[ \boxed{\text{Two jigsaw puzzles and three novels}}
Step 1: Package with 3P must also have 2 other items. Since max novels per package = 3, this package cannot hold 4N. Likely composition = 3P + 2 others.
Step 2: Total novels = 8. If no package >3N, distribution must be 3+3+2 across 3 packages. So each non-3P package must hold either 2 or 3 novels.
Step 3: To satisfy counts, one of the other packages must contain exactly 2 puzzles (balancing the 6 puzzles total).
Answer: The must-be-true statement is (C).
\[ \boxed{\text{One of the other two packages contains exactly two jigsaw puzzles.}} \]
Step 1: Total puzzles = 6. If first two packages contain 2P each = 4 total, then third must contain exactly 2 puzzles.
Step 2: Among options, only (E) has exactly 2 puzzles.
Step 3: (E) = 2G + 2P + 1N, check rules: Games (2) vs Novels (1) ❌ violates rule (games cannot exceed novels). So impossible.
Step 4: (C) also shows 2P, 3N = 5 items, 0 games. This is valid!
Answer: (C).
\[ \boxed{\text{Two jigsaw puzzles, three novels}} \]
Step 1: Total games = 4, distributed across 3 packages with ≥1 each.
Distribution must be 2+1+1.
Step 2: So at least one package has 2 games.
Answer: (A).\[ \boxed{\text{Two games}} \]
Step 1: Novels = 8 must be split into 3 distinct numbers. Possible splits: (1,2,5), (1,3,4), (2,3,3) invalid since not distinct. So one package can have as few as 1 novel.
Step 2: If a package has 1N, it can have max 1G (cannot exceed novels). Remaining items are puzzles. So one package must contain exactly 2 puzzles (because 1N + 1G + 3 left = 2P +1 item).
Answer: (B).\[ \boxed{\text{One package has exactly two jigsaw puzzles.}} \]
