The largest risks while designing a model to withstand a village include that the model does not mitigate the effects of the tsunami or only mitigates the effects partially, which would cause damages to the homes.
Designing a model to withstand the effect of any natural phenomenon such as an earthquake, fire or tsunami is not an easy task and will require the following cycle:
- Designing the model.
- Testing the model.
- Making changes or designing a new model.
In the case of a model for tsunamis, it is likely the following problems occur:
- The model does not protect the houses from tsunamis.
- The model does not protect the houses completely.
This would lead to negative effects such as:
- Damages in the houses.
- Dead or injured people.
- Destruction of infrastrcture.

Answer:
533.33 mg quinine
Explanation:
First we<u> calculate the concentration of the diluted sample</u>, using the values obtained by the standard:
- 288 * 100 ppm / 180 = 160 ppm
Now we use the dilution factors to <u>calculate the concentration of quinine in the original sample</u>:
- 160 ppm * 100mL/15mL = 1066.67 ppm
ppm can be defined as <u>mg of quinine</u>/L solvent:
500 mL solution ⇒ 500/1000 = 0.5 L
- 1066.67 ppm * 0.5L = 533.33 mg quinine
