Set 6: Words in Context (Advanced)
Explanation
PASSAGE
The new algorithm is designed to eliminate ______ data, filtering out noise to ensure that the final output relies only on the most relevant signals.
Which choice completes the text with the most logical and precise word or phrase?
Detailed Answer Explanation
This question asks for the meaning of a word as used in this specific context. Filtering out noise means removing what isn't needed. 'Extraneous' means irrelevant or unrelated to the subject being dealt with. Words can have multiple meanings, and context determines which meaning applies. Read the surrounding sentences carefully. Substitute each answer choice to see which maintains the intended meaning and fits the context. Many vocabulary words have multiple dictionary definitions, but only one fits the context. Use the surrounding sentences as clues. Try substituting each answer choice to see which one preserves the author's intended meaning without changing the sentence's message.
Key Evidence:
• "filtering out noise"
• "relies only on ... relevant"
Why others are wrong: B (Confidential means secret.), A (Encrypted means coded.), D (Essential means needed.).
