Question

based on the origin of the word \knowledgeable,\ the word part \know\ probably means which of the following? to disagree with - he always said know when she suggested a destination for their vacation. to disagree, to deny - her brother was always negative, he never wanted to know the truth. to perceive or understand - she was the only person to know what really happened that day.

Explanation:

The word "knowledgeable" means having knowledge. The root word "know" in English typically relates to having awareness, perception, or understanding of something. Looking at the third option "to perceive or understand", it aligns with the common meaning of "know" as it is about having an awareness or comprehension (which is what knowledge is based on). The first option about disagreeing when suggesting a vacation destination doesn't fit the root meaning of "know". The second option about denying the truth also doesn't match the core meaning of "know" which is about having information/awareness rather than negating.

Answer:

to perceive or understand
