hrxtcnt cannot be an encoding of "science" because the word science has two c's (the second letter and the sixth letter) , and in this word, the second and sixth letter are different (r and n). Therefore, hrxtcnt is not an encoding of science.
tdjfodf is "science" shifted by 1 blrnwln is "science" shifted by 9 nxdzixz is "science" shifted by 21
