A tautogram
from wikipedia :
A tautogram (Greek: tauto gramma, "same letter") is a text in which all words start with the same letter. Historically, tautograms were mostly poetical forms ([1]). The difference between a tautogram and alliteration is that tautograms are a written, visual phenomenon, whereas alliterations are a phonetic one. Most cases of alliteration are also tautograms, though certainly not all since different letters can frequently take on the same sound (e.g., circle segment or Catcher Ken). Similarly, most tautograms are also alliterations, although exceptions exist when using letters with multiple pronunciations (e.g., crazy child or pneumatic plate).
Answer:
The statement is a fact because it contains an expression that can be proven true.
Explanation:
A fact is an opinion that can be proven true whereas a reasoned judgment is an opinion supported by evidence. The statement that the brain activates a greater part of the brain is verifiable from previously conducted studies that were not cited by the speaker. However, his expression was based on that fact. A reasoned judgment would have expressed the opinion and immediately used facts and statistics to support it.
Therefore, the statement is a fact.
