Question

the use of ddt as a pesticide is an example of how new technology can have favorable and dangerous long-term outcomes. how does this relate to the use of dna technology?

only positive outcomes can result from new technology in science.
scientists should conduct long-term studies of dna technology to determine the consequences.
there is no connection because they are different technologies.
scientists should not use new technology; they should use the methods for pest control that are already available.

Explanation:

The example of DDT shows new tech can have mixed long - term effects. For DNA tech, to know its long - term consequences (like DDT's), long - term studies are needed. Option 1 is wrong as new tech can have negative outcomes. Option 3 is wrong as both are new tech with potential long - term impacts, so there is a connection. Option 4 is wrong as new tech can have benefits and avoiding it is not reasonable. So the correct option is the one about conducting long - term studies on DNA tech.

Answer:

B. Scientists should conduct long - term studies of DNA technology to determine the consequences.
