| The scientists were trying to conduct the perfect experiment to test the chemical. |
|
 | We have to make sure the mixture is (homogeneous) so that the results aren't varied. | |
|
| Of course. If it wasn't, it would (inhibit) the results of the test. | |
|

|
|
| The scientists began their experiment. |
|
| The first variable that we should test is this root that is (indigenous) to South Asia. | |
|
| Great. Oh, and be careful not to get it on your skin. It may cause an (inflammatory) reaction. | |
|
|
|
|
|
| After many hours, they had finished their experiment. |
|
| That went better than expected. | |
|
| It was (impeccable). Good job! | |
