PLEASE HELP! GRADES ARE IN TOMMOROW! Evaluating Two Arguments
Read the arguments below.
Then, answer the question about the arguments.
Argument One: Patient 23 felt sick during week 3 because he was infected with the C. jejuni bacteria. From “The Human Microbiome” article, I know that “this kind of C. jejuni infection can cause diarrhea, vomiting, and fever—all the symptoms of food poisoning.” These symptoms match the doctor’s note for Patient 23 for week 3. When Patient 23 felt healthy during week 1, the C. jejuni bacteria was not present in his gut microbiome. In week 3, when he felt sick, C. jejuni was present. Therefore, C. jejuni is probably the cause of his sickness. Argument Two: Patient 23 felt sick during week 3 because he was infected with the C. jejuni bacteria. C. jejuni is very bad for you. He probably ate something spoiled. My sister got food poisoning once.
These two arguments both answer the question Why did Patient 23 feel sick during week 3?
Which of these arguments is more convincing? Explain your thinking below.

On a backpacking trip, kenny hikes all day at a steady pace, covering 30 kilometers and burning 4000 calories. at the school track, janelle runs the 100-meter sprint in 13.5 seconds, burning 10 calories. afterward, janelle’s leg muscles are aching and she is breathing hard, while kenny maintains normal breathing all day, even though he burns 400 times more calories than janelle. which two statements offer the best explanation for this phenomenon? a. if the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt." b. aerobic cellular respiration produces more energy, but its use is limited because of lactic acid buildup in the muscles and the resulting "oxygen debt." c. after about 90 seconds of intense exercise, the muscles become depleted of oxygen, and anaerobic respiration can no longer function to produce atp, resulting in "oxygen debt." d. the rate of energy demand determines how the muscles will obtain energy, either from cellular respiration or from lactic acid fermentation if not enough oxygen is present.
