Question 1189236: Soil contains a wide variety of nutrients, including nitrogen, phosphorus, potassium, magnesium, sulfur, and iron. A fertilizer company conducted an experimental study to determine which of five additives is most effective in helping soil retain nutrients. If, after application of the additives, the fertilizer company tested only for the soil nutrients nitrogen and potassium, which of the following is a valid conclusion?
1. The additive that is found to be the most effective will work for all nutrients in the soil.
2. The additive that is found to be the most effective will work only for nitrogen and potassium.
3. The study is biased and therefore not significantly relevant to determining which additive is most effective.
4. The study will be able to produce results concerning only the effects of the additives on nitrogen and potassium.

You can put this solution on YOUR website! .
This exercise is to check, if you are able to read plain English text, if you do understand
what you read and whether you are able to make simplest logical conclusions from what you read.
Thus, it is highly personalized exercise designed to check your personal skills.
So, this exercise is intended for you PERSONALLY - not for the tutors.
Test yourself, and have happy self-testing ( ! )
Do not disturb the respectful tutors without necessity.

I'd added, that if a person needs help in such an exercise, then he / (or she) should consider to re-visit a kindergarten
