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:  -A photovoltaic cell is created with two layers of semiconductor material -The top layer are &#x27;doped&#x27; with impurities to allow a negative charge -The bottom layer are &#x27;doped&#x27; to allow for a positive charge -This produces an electric field that allows electrons to flow from negative to positve -Sunlight enters the cell -Energy from sunlight knocks electrons loose in both fields -This prevents the flow of electrons from negative to positive -Adding an external circuit allows the exchange to continue -Give the cells owner a flow of electricity.
 Question: What is the effect of a person is in a confined environment with contagious people on more sunlight enters the cell.?

Output: none


Input: Consider Input: Process:  -Water in the clouds becomes very cold -The cold water forms ice crystals -The ice crystals grow by absorbing surrounding water droplets -Form snowflakes -The snowflakes fall to the ground.
 Question: What is the effect of more coal pollution will enter the clouds on more snow.?

Output: none


Input: Consider Input: Process:  -There is a rain cloud in the sky -Small bits of ice within the cloud bump each other -The collisions create electrical charge -Lighter, positively charged particles sink to the bottom of the cloud -Heavier, negatively charges particles rise to the top -When the positive and negative charges grow large enough, a giant spark, called lightning occurs -
 Question: What is the effect of it is very cold in the cloud on less or less powerful lightning.?


Output: against
