CR 1 Seedling growth inhibitors are herbicides that interfere with new plant growth. Plants absorb seedling growth inhibitors from germination until the seedling emerges from the soil, after which point the seedling growth inhibitors can no longer harm the plant. Among the types of seedling growth inhibitor are root inhibitors, which prevent cell division, thereby inhibiting shoot elongation and lateral root formation. Root inhibitors are absorbed through the developing roots and shoots which receive the bulk of the damage to the plant.
Which of the following, if true, would most strongly support the position that it is inadvisable to protect corn crops by using root inhibitors on weeds vulnerable to the herbicide?
A The seedlings of corn plants generally appear above the soil before the shoots of the weeds common in corn crops.
B. Most weeds are susceptible to some type of herbicide.
C. Not all weeds can be eradicated by root inhibitors.
D. The root inhibitors can damage the roots and shoots of plants beneficial to corn plants as well as any unwanted plants.
E. Although botanists have developed root inhibitors in the lab and tested them in the field, there is no major production facility producing them.

CR 2 Consumer Advocate: Happy Smiles Daycare, a popular child-care facility in Rolling Hills, boasts an average child-to-caregiver ratio of 5:1, a number it cites as the lowest in the county. Furthermore, the daycare claims that compared to some other daycare centers in the county, it does not include helpers, or those who are involved in cleanup and diaper changing, when computing the ratio. Yet Happy Smiles Daycare’s claim that parents with children aged 1–3 will find no other facility with such a low child-to-caregiver ratio is not accurate.
Which of the following, if true, provides the best justification for the Consumer Advocate’s position?
A. Happy Smiles Daycare has two rooms, one for children 1-2 years old and another for those 2-3 years old, both of which have a child to caregiver ratio of 5:1.
B. Kenton School, which has fewer than 100 students and a legitimate child-to-caregiver ratio of 6:1, provides approximately equal-sized classes for each year up to age 6, though the classes for those over 3 have a child-to-caregiver ratio more than double that of the other classes.
C. The number of students enrolled in Happy Smiles Daycare remains relatively fixed throughout the year.
D. Tiny Tots Daycare, which boasts a 4:1 child-to-caregiver ratio, includes any adults who are in a classroom throughout the day.
E. Looming budget cuts indicate that Happy Smiles Daycare may not be able to sustain such a low child-to-caregiver ratio in coming years.
