This is a dubious question, and deserves a challenge. All the sentences can come together and form a coherent paragraph. 'this factoid' in statement 2 can be found in statement 5 . Thus 5 and 2 form a pair. 1 opens the paragraph. Impossibility of translation in 3 and impossibility of bumblebee flight are connected. Thus 1523 form a coherent paragraph. Statement 4 can come in the concluding lines. This question has no odd sentence. The source of the passage can be found here
