A group of mountain climbers was studied to determine how they were affected by diminished oxygen in the air at high altitudes. ██ ████ ███████ ████ █████ ██████ █████ ███ ██████ ███ ████████ ███████ ██████ ████ ██████ ██ ██████████ ██████ ██████████ ███ ████████████ ████ █████████ ████ ███████████ ██ ████████ ████████████ █████████ ███ ██████ ████ ███ ████ ██ ███ █████ ███████████ ██████ ██ ████████ ████ ████ ███████████ █████ ██████████
Summarize Argument
The author concludes that the area of the brain controlling speech is not distinct from the area controlling other functions. He supports this by noting that the mountain climbers in the study slurred their speech, took longer to understand simple sentences, and showed poor judgment after climbing above 6,100 meters.
Identify and Describe Flaw
The author concludes that the area of the brain controlling speech isn’t separate from the area controlling other functions because multiple brain functions worsened at high altitudes. He assumes that all these functions are controlled in the same area, ignoring the possibility that multiple areas could have been affected by the altitude.
In other words, the altitude might have impacted multiple distinct brain areas, or the entire brain, affecting both speech and judgment, even though they are controlled in distinct areas.
