Genetically modified crops and livestock offer the possibility of greater yield and food quality, reductions in pesticide use, and higher profits for agricultural businesses. They are viewed by some as a way to help reduce world hunger by increasing food production and reducing losses to pests and varying environmental conditions. Each year, industrial agriculture relies more heavily on genetically modified crops. There are some concerns about our increasing use of genetically modified crops and livestock, including their safety for human consumption and their effects on the environment.
Based on the passage above, if genetically modified crops were to be banned, what could be the largest negative impact to humans?
Explanation
The passage indicates that genetically modified crops offer the possibility of greater crop yield. If genetically modified crops were to be banned, the conclusion is that there would be less food available.
Battery companies make impressive claims about how long their batteries will last. A student decided to test the running time of different batteries to determine which battery lasts the longest. The student tested 6 different batteries, 4 brand name and 2 generic, using flashlights. The results show that the battery referred to as Name Brand A lasted the longest, with 101 hours of runtime:
Flashlight | Battery | Runtime in hours |
Gearlight Super Light | Name Brand A | 101 |
SureFire | Name Brand B | 99 |
Maglight | Name Brand C | 80 |
Bright Star | Name Brand D | 75 |
SureFire | Generic A | 30 |
Bright Star | Generic B | 29 |
It could be argued that this experiment was not set up using proper experimental protocol. What would need to change in the experiment for the results to be valid?
