Answer:
I'm assuming you meant pool instead of poolon, i'll take it as a grammatical error. Anyhow, the water in a pool on sunny days tend to have less chlorination then on regular days. This is because chlorine forms hypochlorite ions in the water, and these are broken down by the ultraviolet light from the sun. Rainy or shiny, the weather is always affecting the chemistry in your pool.
Now, if you want to get more complicated into it, you can add a stabilizer into the pool. The common one safely used in pools is cyanuric acid. This almost completley prevents all de-chloronification.
I hope this information was of any use to you.

Answer: Option C
<u>Explanation:</u>
The Soil and Water Conservation Act is a 1977 law which required the the US Department of Agriculture to periodically draw up national plan for soil and water conservation on private lands based on an inventory and appraisal of existing resource conditions and trends.
Natural Resources Conservation Service is the lead agency who has completed its first and the second appraisals in the early and the late 80s and the last appraisal was started in the early 90s but unfortunately it was not finished.
