In this task you will be given a process, and a question. The process contains a sequence of steps that happen in order. The question asks about the effect of a certain event on another event. If the first event has a positive effect on the second event, answer with "for", if it has a negative effect, answer with "against". If there's no causal relationship between the two, answer with "none".

Input: Consider Input: Process:  -Prophase is the first and longest stage of mitosis -In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell -In prophase the chromosomes become visible and the centrioles separate and move to opposite poles of the cell -In metaphase the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere -In anaphase the sister chromatids separate into individual chromosomes and are pulled apart -During telophase the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes -Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear.
 Question: What is the effect of if during anaphase sister chromatids separate on the process of mitosis will decrease.?


Output: against
