Zorluk: OrtaNegative Factual and EXCEPT Questions

Passage:
During the early nineteenth century, geologists debated the mechanisms responsible for the distribution of erratic boulders across northern Europe. Diluvialists posited that immense cataclysmic floods, generated by oceanic inundations, had swept massive granite blocks across vast distances. In contrast, early drift theorists argued that icebergs floating across submerged continents transported these erratics, dropping them onto the sea floor as the ice melted. Both hypotheses accounted for the marine fossils found alongside erratics, yet both failed to explain the pronounced striations on underlying bedrock.

Louis Agassiz introduced the glacial theory in 1837, contending that expansive continental ice sheets had carved the bedrock and dragged the boulders directly across land. Initially met with skepticism by established geologists who favored iceberg transport, Agassiz's continental ice sheet model gained momentum when researchers identified modern glacial scours in the Alps identical to northern European bedrock patterns. Furthermore, Agassiz demonstrated that erratic distribution coincided precisely with terminal moraine boundary lines, a pattern that random iceberg floating could not produce. Nevertheless, Agassiz's original formulation incorrectly assumed that global cooling was driven by sudden solar atmospheric blockages, a mechanism later disproved by nineteenth-century thermodynamic physics.

Based on the passage, evaluate the following statement as True or False:
Statement: Louis Agassiz's glacial theory accurately identified the physical cause of global atmospheric cooling.

Cevap: Cevap

Cevap

The statement is False.
The statement is false because the passage explicitly affirms that Agassiz's proposed mechanism for global cooling was an incorrect assumption that was subsequently disproved by nineteenth-century physics.

Adım Adım Çözüm

1
Locate the specific passage evidence regarding Louis Agassiz's explanation of global cooling.
The final sentence states: 'Agassiz's original formulation incorrectly assumed that global cooling was driven by sudden solar atmospheric blockages, a mechanism later disproved by nineteenth-century thermodynamic physics.'
Negative factual evaluation requires verifying statement claims directly against explicit passage assertions.
2
Compare the statement's claim with the textual evidence.
The statement asserts that Agassiz accurately identified the cause of global cooling, which directly contradicts the text's explicit statement that he incorrectly assumed the cause.
A statement that is directly contradicted by explicit text in a reading comprehension passage is false.
