Difficulty: Easy
Correct Answer: 4
Explanation:
Introduction / Context:
Everyday cooking and kitchen measurements often use standard units like cups, pints and quarts. Knowing how these units relate to each other is helpful both in daily life and in general knowledge exams. This question asks for the number of cups in one quart in the commonly used imperial or United States system.
Given Data / Assumptions:
Concept / Approach:
In the United States customary system, 1 quart equals 2 pints and 1 pint equals 2 cups. Combining these relationships, 1 quart equals 4 cups. This relationship is often shown in kitchen measurement charts and on measuring jugs. Therefore, the correct answer is that there are 4 cups in 1 quart.
Step-by-Step Solution:
Step 1: Recall the basic conversion 1 pint equals 2 cups.
Step 2: Recall that 1 quart equals 2 pints.
Step 3: Multiply 2 cups per pint by 2 pints per quart to get the number of cups per quart.
Step 4: This gives 2 times 2 equals 4 cups in 1 quart.
Verification / Alternative check:
Another check is to remember the common mnemonic used in some schools where a large Q stands for quart, which contains two P symbols for pints, and each P contains two C symbols for cups. Visually this shows four C symbols inside one Q. This simple diagram confirms that there are 4 cups in 1 quart.
Why Other Options Are Wrong:
Option A, 2 cups, would correspond to 1 pint, not 1 quart.
Option B, 3 cups, does not match any standard whole unit conversion.
Option D, 1 cup, is far too small and equals only a quarter of a quart.
Option E, 8 cups, would equal 2 quarts or half a gallon, so it is double the correct value.
Common Pitfalls:
Learners may mix up pints and quarts or confuse the imperial and metric systems. A simple way to avoid this is to remember the chain in order: 1 gallon equals 4 quarts, 1 quart equals 2 pints, and 1 pint equals 2 cups. Keeping this ladder clear in your mind helps you answer any related conversion question quickly.
Final Answer:
One quart contains 4 standard cups.
