What process has had the greatest effect on the genetic makeup of modern crops?
- Genetic engineering
- Selective breeding
The first plant to be genetically engineered was:
- Arabidopsis
- duckweed
- alfalfa
- tobacco
- bentgrass
What was the first GM crop approved for cultivaton?
- corn (maize)
- cotton
- tomato
- soybean
- canola
When did crops become resistant to herbicides?
- After the introduction of Bt corn (maize) in 1997
- After the introduction of Roundup-ready soybeans in 1996
- When herbicides were first invented.
Human intervention is required to transfer genes between species.
- Yes
- No
On average, how long does it take to develop a new engineered crop and release it for cultivation?
- 20 years
- 10 years
- 5 years
- 1 year
Tomato paste from engineered tomatoes is no longer available in Britain, because:
- The tomatoes caused organ damage in rats.
- The tomato paste caused allergic reactions in humans.
- Consumers rejected paste made from the tomatoes
- Regulations were changed, which made it impossibly expensive to grow the tomatoes in the European Union.
StarLink corn (maize) and foods made from it were pulled from the market because:
- it caused allergic reactions in humans.
- the pollen killed Monarch butterflies.
- it was only approved for animal feed.
What country has approved the greatest number of GMOs for food and feed?
- USA
- Japan
- South Korea
- Australia
The farmers who derive the greatest direct benefits from engineered crops are those in:
- wealthy developed nations.
- nations with lax regulations
- resource-poor farmers in developing nations.
What are popular reasons for farmers to purchase engineered seeds?
- increased yields
- decreased input costs.
- reduced management time
- reduced soil erosion
- all of the above.
How many published studies have concluded that engineered crops are safe for production and consumption?
- 50+
- 100+
- 200+
- 400+
Engineered potatoes have been developed in the US, but are not grown there, because:
- they caused stomach lesions in lab rats.
- they caused damage to biodiversity.
- consumers rejected them.
- French fry manufacturers rejected them.
Food crops with the 'Terminator' gene:
- produce sterile seed.
- prevent piracy of patented seed.
- prevent spreading of genes to other crops or plants.
- all three of the above.
- do not exist.
By 2008, field trials of engineered plants which had been conducted in the US totaled roughly:
- 2,300
- 6,300
- 12,300
- 14,300
By 2008, the number of field trials of GMOs that had been conducted in the European Union totaled roughly:
- 200
- 400
- 1,400
- 2,400
Engineered wheat is not grown anywhere, because:
- consumers would not accept it.
- growers would reject it.
- it would destroy biodiversity.
- wheat exporting/importing corporations rejected it.
The number of farmers who have been sued because engineered pollen or seed got into their fields by accident total roughly:
- 50
- 100
- 300
- zero
Biotechnology corporations control the food supply, by:
- forcing farmers to buy GM seed.
- suing farmers because GM seeds or pollen accidentally fall on their crops.
- patenting their seeds.
- not labeling GM products.
- none of the above.
Large Scale Biology Corporation developed a wide variety of plants for the production of pharmaceuticals at lower cost. The company folded, because:
- physicians would not prescribe the pharmaceuticals.
- patients would refuse to take pharmaceuticals that come from GM plants.
- health insurance companies refused to cover the cost of pharmaceuticals from GM plants
- there was no incentive to produce pharmaceuticals at lower cost.
GM crops cannot 'feed the world', because
- there's already enough food.
- infrastructure, such as transportation and storage, are lacking.
- people think it can't be done, and some will do nearly anything to make sure it doesn't happen.
