Understanding Homonyms in Sentences

This question tests our understanding of homonyms, which are words that are spelled the same (and sometimes sound the same) but have different meanings. The underlined word in the sentence is "lead". We need to find another sentence that uses a word spelled "lead" but with a different meaning and pronunciation.

Analyzing the Underlined Word "Lead"

In the sentence "The lead pipes were replaced due to safety concerns," the word "lead" refers to the metallic element (symbol Pb). This word is pronounced /lɛd/.

There is another common word spelled "lead" which means to guide or be in front. This word is pronounced /liːd/. This is the homonym we are looking for.

Evaluating the Options

Let's examine each option:

• Option 1: "The general will lead the troops into battle."

  Here, "lead" means to guide or direct. This is pronounced /liːd/. This is a different meaning and pronunciation from the "lead" in "lead pipes" (/lɛd/). Therefore, this option uses a homonym.

• Option 2: "Exposure to lead can cause health issues in children."

  In this sentence, "lead" refers to the metallic element, just like in the original sentence. It is pronounced /lɛd/. This is not a homonym.

• Option 3: "The old house still had lead in its plumbing system."

  Similar to option 2, "lead" here refers to the metallic element (Pb) and is pronounced /lɛd/. This is not a homonym.

• Option 4: "They tested the soil for traces of lead."

  Again, "lead" in this context refers to the metallic element, pronounced /lɛd/. This is not a homonym.

Conclusion on Homonym Usage

The key is to identify the sentence where "lead" has a different meaning and pronunciation compared to its use as a metal in "lead pipes". Only the first option correctly uses the verb form "lead" (/liːd/), which is a homonym of the noun "lead" (/lɛd/).
