Read the rough draft of a student’s conclusion to an argumentative editorial.(1) Year-round schooling would help student achievement. (2) Not so much information would have to be crammed into nine months. (3) Furthermore, the elimination of long breaks, particularly summer break, would significantly reduce "learning loss” and the additional time wasted at the beginning of each academic year to reteach previously learned material. (4) It is clear that year-round schooling helps students learn and retain more. (5) The United States is not the only country to experiment with a year-round school schedule. (6) Although many still claim that evidence about year-round school and its link to higher achievement is inconclusive, these people need to open their eyes and see that students in these schools consistently score higher on certain assessments than students who attend schools with traditional nine-month calendars. (7) It is about time that we replaced our outdated and inefficient school calendars.

A
Although many still claim that evidence about year-round school and its link to higher achievement is inconclusive, studies consistently reveal that year-round students score higher on certain assessments than those students who attend schools with traditional nine-month calendars.
B
Although many still claim that evidence about year-round school and its link to higher achievement is inconclusive, this theory is wrong because students in year-round schools consistently score higher on certain assessments than those students who attend schools with traditional nine-month calendars.
C
Although many still claim that evidence about year-round school and its link to higher achievement is inconclusive, they would admit defeat if only they would do their research and find that students in year-round schools consistently score higher on certain assessments than those students who attend schools with traditional nine-month calendars.
D
Although many still claim that evidence about year-round school and its link to higher achievement is inconclusive, these people need to study their facts and acknowledge that students in year-round schools consistently score higher on certain assessments than those students who attend schools with traditional nine-month calendars.

Read the sample student claim and the reasons listed for making this claim.Claim: Although many people argue that medical testing on animals is a violation of animal rights, the benefits it yields for society far outweigh any argument that can be made.Reason #1: Animal research has yielded both pain-relieving and life-saving drugs for humans.Reason #2: Laws prohibit scientists from using animal-based research in cases where non-animal testing would produce equally clear and valid results.

A
The history of using animals for research extends as far back as 322 BCE, when early Greek physician-scientists, such as Aristotle and Erasistratus, performed various experiments on living animals.
B
Animal research played an essential role in the development of Herceptin and Tamoxifen, two medications that have already saved the lives of thousands of women who have been diagnosed with breast cancer.
C
Even those who believe in testing on animals when it is necessary for vital medical research practice what is known as “the 3 Rs”—reduction, refinement, and replacement—to reduce the number of animals used for testing.
D
Biologists believe that chimpanzees share at least 98.4 percent of the same DNA as humans and gorillas share at least 97 percent, making primates a popular and likely choice for the testing of products intended for humans.
