A word-and-number arrangement machine, when given an input line of words and numbers, rearranges it in steps. In each step the rightmost unshifted word of five letters or more is taken out and placed at the extreme right end of the line. Words of fewer than five letters, and all the numbers, are never shifted; every other element keeps its relative position, and the machine stops when no such word is left. Input: neem 63 banyan 27 mandir 48 tulsi ghat 35. Which of the following is Step 2 of the above arrangement?

Question
