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

Explanation:

• The first option is incorrect because new technology can have both positive and negative outcomes, not just positive.
• The second option is incorrect as not using new technology is not a practical approach; instead, proper study and assessment should be done.
• The third option is incorrect as there can be connections between different technologies in terms of the need for understanding long - term impacts.
• The fourth option is correct. Just like DDT (where long - term dangerous outcomes were later discovered), for DNA technology, scientists should conduct long - term studies to determine its consequences.

Answer:

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