Chapter 21 Exercises

. The below statement would be considered a bad statement of need.
Salamander limb deformities detected in California are of concern to public health experts. It is important to explore the underlying causes of these deformities to establish preventive measures. An urgently needed next step in the protection of public health is the examination of the X hypothesis. Investigations of this hypothesis may not only determine the causative agent of the observed limb deformities but also forgo the danger of potential developmental problems in humans.

True

False

. The below objective statement demonstrates good wording.
We propose to use a novel class of experiments to test nearly every theoretical prediction of T-violation that can account for the matter-antimatter asymmetry in the universe.

True

False

. The below statement would be considered a good impact statement.
Understanding the interaction between HCV virions and the extracellular milieu is critical for combating this virus. These interactions can be illuminated by defining the biochemical composition of the virus particles, elucidating the mechanism of their assembly and maturation, and determining the differences in the entry of high-infectivity, low-density particles to those of low-infectivity, high-density particles. Insights into these mechanisms will contribute to developing new drugs and vaccines to combat this major human pathogen.

True

False

. The below statement would be considered a bad impact statement.
Novel, bioengineered crops will allow farmers to grow varieties of plants with enhanced productivity, quality, and improved ability to adapt and survive when faced with adverse environmental conditions. This need is particularly urgent in light of the global food crisis, which has put almost a billion people at risk of hunger and malnutrition. By designing new technology and developing varieties that allow more sustainable farming, the project aims to provide innovative and sustainable solutions to the problems faced by crop growers worldwide.
