The study shows that first-year language students at Jones speak more fluently after just

colleges at graduation. Despite these impressive statistics, I am unconvinced by this

However, we are not given enough information about the study to be sure that this
& \ J1 U; b5 K, {+ l# T3 e9 @comparison is reliable. For example, the article does not tell us whether the foreign 7 A/ L4 d1 U8 B; \
language students at Jones were given the tests; it only reports that the tests in question 0 m; O+ y; l5 h3 G" m. f& z
were "given to students at 25 other colleges." If Jones students were not tested, then no

Furthermore, we cannot tell from this article whether the universities in the study, 2 G2 K5 S. u& P @" L' `
or their students, are comparable in other ways. For instance, Jones might be a A2 \+ a& S% x2 G* c

graduates, while the other universities are lower-ranked schools with more lenient

about Taylor's program. To strengthen the argument, the author must show that the
