Answer:

The correct option is;

D) Observational study

Explanation:

In an observational study, the researcher observes, notes and record the an occurrence of events which are due to the existence of a condition, test, risk factor, such that the experimental units are apparently out of the control of the researcher, or there are no researcher intervention in the study, due to either physical constraint or laid down ethics.

I will give brainliest if u write a story!!!!! imagine that you were flying a small aircraft alone and had to make an emergency
nikitadnepr [17]

I would rather land at a Temperate Coniferous forest, as I can use wood, except that it has more space to move in, unlike a Taiga (Probably). I would want medkits, water, non-perishable food, Radio, and a Flashlight for the Dark. I would build campfires, hunt for food to eat, and protect myself safely, by building forts, by gathering leaves and wood. I would do other stuff like an average stranded person would usually do to survive. When I was flying that aircraft, and I saw that its damaged, and wit wouldn't fly, I would panic, and look quickly for an efficient place to land on. I would gather Resources to fix my aircraft (If it's possible and/or allowed for this story). Coniferous forests are slow growers, so this damage is irreparable. Another threat is deforestation; even when trees are replanted they are typically one species, leading to monoculture, and they are slow to grow back. This loss of trees contributes to erosion, loss of habitat, and lack of diversity. Those are the dangers I think.

Nine less than four times a number equals fifteen
Natasha_Volkova [10]
Simple
Nine less than a number times four equals fifteen
basically, x*4-9=15 would be your equation, or something similar
Well, we know x can't equal 1,2,3,OR 4. Five is also out, because 5*4=20-9=11, so cross that out.
But if you try doing 6*4-6=15, it fits.
6*4=24, 24-9=15
Thus, x=6, so your answer to Nice less than four times a number equals fifteen is 6. 
~Hope this helps!
