<span>Alright.. this is what I have in mind... then you can judge if I'm totally crazy:
As in any other experiment we wish to only hold 1 variable, while other thinkable variables are held constant.
In addtion to that we need to ref. soil and call that 0.
Now some theory: We know from medicals they can have synergetic effect if mixed. Same can go for nutrients, we therefor test each soil mixed and alone and see the effect.
We call the nutrients A, B and C, (continue with more if you like)
Now this is our setups:
0, A, B, C, AB, AC, BC, ABC.
In this way we can make compare to a ref soil (0) and also check for synergetic effects... this is a bit considered a multivariable experiment, but we also have A, B and C as ref. against the mixed soils.</span>
Answer:
Option (4)
Explanation:
Tsunamis are usually defined as the large and extensive wave that occurs in the oceans and seas due to the occurrence of an earthquake below the oceans, underwater landscape and other strong volcanic explosions.
They are mostly initiated by earthquakes, and these types of disasters are unpredictable. The movement of seismic waves is responsible for the generation of tsunamis over the ocean water body. The occurrence of tsunamis is somewhat predictable, by observing the changes that occur in terms of the height of sea level. By making these observations, immediate warnings are given, and the coastal areas are vacated at the earliest.
These tsunamis produce larger or smaller waves depending on the magnitude of the earthquake.
Thus, the correct answer is option (4).
Answer:
Probably because it either has inappropiate language or has been traced back to a test.
