Numerical answer
The following paragraph has five sentences, numbered 1-5. Four of them form a coherent paragraph when arranged correctly; one sentence does not belong at all. Identify the sentence number that does not fit.
1. Beekeepers have long known that a hive's productivity depends heavily on the health and fertility of its single reproductive queen.
2. When a queen's egg-laying rate declines, worker bees will often begin raising a replacement by feeding a selected larva an exclusive diet of royal jelly.
3. Royal jelly is a protein-rich secretion produced by worker bees from glands in their heads, and its composition changes with the age of the worker producing it.
4. This replacement process, called supersedure, allows the colony to maintain productivity without the disruption of losing its queen entirely, since the old and new queens may briefly coexist.
5. Commercial beekeepers sometimes intervene directly, introducing a pre-mated queen from a breeding programme instead of waiting for the colony to raise its own.

Show answer and solution
Answer: 3
Sentences 1, 2, 4 and 5 form a coherent account of queen replacement (decline in productivity leads workers to raise a replacement using royal jelly, called supersedure, and beekeepers sometimes intervene). Sentence 3 is a factual aside about the composition of royal jelly itself; it does not advance the narrative about queen replacement and interrupts the logical flow between sentence 2 and sentence 4, which continues discussing supersedure. It is the odd one out.
