stepan [7]

Explanation:

Accuracy is the proximity of the data to the value considered as real, in this situation we do not know the real value and we do not know if the data is accurate or not, so we can discard options b and d.

Now, precision is the proximity of the data obtained among themselves and that is what we can observe, so the appropriate answer is the option a.

How does advertising affect the sales of orbit white
MAXImum [283]
It would get the news out about Orbit White, and people would hear about it, and/or see the advert.  They might even want to buy it or go into the grocery store thinking about it and end up buying it. 

I hope I didn't misread the question because this looks more like an English/ Social Studies question than a chemistry question.
