Which is not a concern about GM food?
GM food may cause allergy.
GM food can be produced in higher yields and at lower production costs.
The long-term effects of consuming GM food on health are unknown.
Vegetarians may unknowingly consume food that contains animal genes.
Which is not an environmental issue raised by biotechnology?
Farmers only concentrate on planting profitable GM crops and thus biodiversity is adversely affected.
GM crops are better adapted to the environment and thus may replace their wild types.
GM crops may compete with the other plants in the same habitat.
Planting insect-resistant GM crops may cause less chemical pollution.
Which is not an advantage of growing GM crops?
The nutritional value of GM crops is higher.
The shelf life of GM crops is longer.
GM crops are more resistant to pests.
GM crops can out-compete their natural counterparts.

Which of the following statements about cloning are correct?
(1) Endangered species can be conserved by cloning.

Which statements about gene therapy is correct?
The cost of gene therapy can be afforded by the general public.
Gene therapy brings concerns about the right to modify one’s genetic make-up.
Gene therapy is banned in all countries.
Gene therapy is proved to have no long-term side effects on patients.
Which is not a reason against somatic cell gene therapy in treating genetic diseases?
Repeated treatments are needed regularly.
The introduced gene will not be passed onto the offspring.
The process of natural selection will be interfered by humans.
The genetic make-up of the patient’s offspring is modified.
Which is not a dispute over genetic testing?
People can choose whether or not to receive genetic testing for disease-related genes.
People may live with distress if they are diagnosed of carrying disease-related genes.
Parents can screen the genetic makeup of embryos and abort the embryos with genetic defects.
Disclosure of personal genetic information may cause discrimination against the people with genetic abnormalities.
Which of the following descriptions about stem cell transplant are correct?
(1) The operation cost is very high and cannot benefit the general public.
(2) The transplanted stem cells will not be rejected by the patient’s body.
(3) The use of human embryos has caused controversy.
