Discussion
From the word 'POSTSCRIPT', how many independent words can be made without changing the order of the letters and using each letters only once?
Answer: B
Correct answer: 2
Keeping the letters of POSTSCRIPT in order and using each once, the word divides into two: POST and SCRIPT.
The division is clean, using all ten letters with none repeated and none moved. That completeness is what makes it the intended answer - a third word would need a letter used twice or taken out of sequence, and the question forbids both.
