A Text 1 reports the exhibit reached 19 students across 16 schools in a semester but admits the pilot was limited. Text 2 adds that teachers reported higher interest, but handling rules were needed to prevent damage and cautions that replicas helped protect fragile originals. Together, the texts suggest building a small traveling exhibit for schools has potential, but Stonepark should gather more evidence before making a sweeping claim.
B Because Text 1 reports the exhibit reached 19 students across 16 schools in a semester, the best conclusion is that building a small traveling exhibit for schools will have the same results everywhere, even though Text 2's result that teachers reported higher interest, but handling rules were needed to prevent damage depends on conditions.
C Text 1 reports the exhibit reached 19 students across 16 schools in a semester and Text 2 reports teachers reported higher interest, but handling rules were needed to prevent damage, so Stonepark can conclude the plan caused every improvement and will work in all settings.
D Text 2 mentions replicas helped protect fragile originals, so the pilot results in Text 1 (the exhibit reached 19 students across 16 schools in a semester) do not matter and building a small traveling exhibit for schools should not be tried again.
