Q: Answer-In each of the question below, four sentences are given. Find out which of the following sentences i...

Sentence A Correct has been demonstrated correctly uses the present perfect passive with the singular subject neuroplasticity. Well into old age is correctly positioned as an adverbial modifier. Sentence B Incorrect Rule The indefinite article an not a must be used before words beginning with a vowel sound. Individual begins with the vowel sound . Article used a individual incorrect a precedes consonant sounds only. Correct article an individual This is a straightforward article usage error that significantly marks the sentence as incorrect at an advanced level precisely because the surrounding sentence structure is sophisticated enough to conceal it from careless readers. Sentence C Incorrect Rule A relative clause describing an ongoing, present scientific phenomenon must use the present tense verb not the simple past since the phenomenon continues to operate in the present. Verb used pathways that mediated the subjective experience simple past incorrect for describing a continuously active neurobiological mechanism. Correct verb pathways that mediate the subjective experience present tense, capturing the ongoing physiological process. The rest of the sentence correctly uses present perfect has been reconceptualised and present progressive constructions, making mediated a conspicuous tense inconsistency within an otherwise well-formed sentence. Sentence D Correct challenges, are not exclusively implemented, and are fundamentally shaped all correctly use present tense for a theoretical claim about cognitions general character.

(
C The placebo effect, long dismissed as a mere confound that clinical trial methodology was designed to control for, has been reconceptualised by contemporary psychobiological research as a genuine neurobiological phenomenon involving measurable changes in endogenous opioid activity and dopaminergic pathways that mediated the subjective experience of symptom relief. (
D Embodied cognition theory challenges the classical computational model of mind by proposing that cognitive processes are not exclusively implemented in the brain but are fundamentally shaped by the configuration of the body, the dynamics of motor activity, and the structure of the physical environment within which cognition occurs.
