Question

a recurring image pattern has appeared in recent brain - scan analyses focused on how motion is processed in the visual cortex. one interpretation links the nearby circular signal to neural sensitivity toward rotational movement, citing similar results in controlled experiments. neuroscientist lila moreno, however, argues that the pattern may arise from general signal clustering rather than motion specialization. ___ the circular feature cannot be treated as definitive proof of a rotation - specific mechanism.

which choice completes the text with the most logical transition?
a regardless,
b to this end,
c nonetheless,
d on that basis,

Explanation:

To determine the correct transition, we analyze the logical relationship between the previous statement and the conclusion. Neuroscientist Lila Moreno argues the pattern comes from general signal clustering (not motion specialization). The conclusion that the circular feature isn't definitive proof of a rotation - specific mechanism follows from this argument.

• Option A "Regardless" implies ignoring the previous statement, which doesn't fit as the conclusion is based on the argument.
• Option B "To this end" is used to show a means to achieve a goal, but here we are drawing a conclusion from an argument, so it's incorrect.
• Option C "Nonetheless" is used to show a contrast or contradiction, but there is no contradiction here; the conclusion is a result of the argument.
• Option D "On that basis" means using the previous argument as a foundation for the conclusion, which matches the logical flow here.

Answer:

D. On that basis
