Support Three-year-old Sara and her playmate Michael are both ill and have the same symptoms. █████ ████ ████ ████████ █████ ██████████ ████ ████████ ███ ███ ████ ███████ ██ ███████ █████ █████ ███████ ██████████ ████ ███ ████ █ █████████████ ██████████ ███████ ███ ██████ ████ ████████ ██ ████ ███ ███████ ████ ████ ███ ██ ██████████ ███ █ █████████████ █████████ ███████
The author concludes that Sara definitely does not have a strep infection, despite having some symptoms of one. Why? Because Sara has the same symptoms as Michael, and the two of them play together every day. This leads to the sub-conclusion that Sara probably has the same illness as Michael. And Michael definitely doesn’t have a strep infection.
The author draws a conclusion about what must definitely be the case based on evidence about what is probably the case. The conclusion is that Sara “definitely” doesn’t have strep, because Michael definitely doesn’t have strep. However, Sara and Michael only “probably” have the same illness.
