In the following question, select the one word that best substitutes the given phrase: “A place where animals are slaughtered for consumption as food.”

Introduction / Context:
This one word substitution question asks you to find a single term that replaces the phrase “a place where animals are slaughtered for consumption as food.” The correct term is a specific noun used in agriculture, meat industry regulation and public health contexts. Knowing such words helps in understanding news reports and formal documents relating to food production and regulation.

Given Data / Assumptions:

• The phrase describes a physical place where animals are killed and processed to provide meat for human consumption.
• Abattoir is a noun that means a slaughterhouse, specifically a place where animals are killed for meat.
• Reservoir refers to a large natural or artificial lake used as a water supply.
• Memoir is a written account of someone's personal experiences.
• Peignoir refers to a type of loose dressing gown or negligee worn by women.
• Only one of these words refers to a killing place for animals used as food.

Concept / Approach:
To solve this item, identify that the key idea is a location where slaughter for food occurs. Words related to water, clothing or writing clearly do not fit. Abattoir, borrowed from French, is the technical English term for slaughterhouse. If you know that reservoir connects to water and memoir to memories, it becomes easy to eliminate those choices and select the only term associated with animal slaughter.

Step-by-Step Solution:
Step 1: Focus on the phrase “animals are slaughtered for consumption as food.” This indicates the meat industry and a slaughterhouse. Step 2: Consider Abattoir. It is defined as a place where animals are killed for their meat, exactly matching the idea of a slaughterhouse. Step 3: Evaluate Reservoir. It describes a storage area for water, such as a lake or artificial pond, not a place for slaughter. Step 4: Examine Memoir. This is a literary term meaning a written narrative of personal experiences. It is unrelated to places or animals. Step 5: Check Peignoir. This refers to a woman's loose dressing gown, which clearly does not describe any kind of building for animal slaughter. Step 6: Since only Abattoir accurately describes the place in question, it is the correct answer.

Verification / Alternative check:
Imagine the word being used in a news report: “The city council inspected the abattoir to ensure hygiene standards.” This aligns perfectly with the concept of animals being killed for food. Substituting Reservoir, Memoir or Peignoir in this sentence would make the statement absurd. Dictionary definitions also confirm that Abattoir is synonymous with slaughterhouse.

Why Other Options Are Wrong:
Reservoir is a water storage facility, Memoir is a book of memories, and Peignoir is an item of clothing. None of these words contains any meaning related to killing animals or processing meat. Correct professional or legal usage requires the term Abattoir when referring to such facilities, so picking any other option would misrepresent the phrase given.

Common Pitfalls:
Because Abattoir is less frequently used in everyday speech, students sometimes confuse it with Reservoir, which is a more familiar term. A helpful strategy is to remember that the syllable ab in Abattoir is related to the French verb abattre meaning to strike down or kill. Linking this root to the idea of slaughter will help you recall the correct word in future questions.

Final Answer:
The correct one word substitute for “a place where animals are slaughtered for consumption as food” is Abattoir, so the correct answer is option Abattoir.
