The correct answer is - the variable.
With the experiment, in the way that Dan had decided to perform it, the fertilizer is the variable, as in one of the parts with strawberries he uses fertilizer, while in the other part he doesn't uses fertilizer.
While this kind of experiment may give Dan some answers, and he might notice differences, still he would have to be more detailed in the experiment to see for sure if the fertilizer is the thing that makes some of the strawberries grow better than the others.
Dan should also put all of the strawberries at places that would receive the same amount of light, experience the same weather conditions, receive the same amount of water, and to be planted in a soil of the same quality. Only like this, after putting the fertilizer, Dan can now if it makes any changes or not.
The correct answer is low precipitation.
The cause of limited water supplies is reduced precipitation or low precipitation.
Precipitation is termed as any product of condensation which is of atmospheric water vapour which falls under gravity.
Forms of precipitation can be sleet, snow, graupel, hail, drizzle, and rain.
Precipitation occurs when portion of atmosphere comes to being saturated with water vapor such that water condenses and then it precipitates.
It is the major component of water cycle and deposits fresh water to planet.

Passing through clay beds affect groundwater because it will take time for it to pass and penetrate through clay. Water cannot pass deeper to get across, the direction is horizontal to the most penetrable part of the soil where it can pass.
