The question asks us to identify the word that is different from the others in the given list: Intelligence, Weight, Aptitude, and Memory. We need to find the common characteristic among three words and identify the one that does not share that characteristic.

Understanding the Given Words

Let's look at the meaning of each word:

• Intelligence: The ability to acquire and apply knowledge and skills; mental ability.
• Weight: A body's relative mass or the quantity of matter contained by it, giving rise to a downward force; a measure of the heaviness of an object. This is a physical property.
• Aptitude: A natural ability to do something; a natural tendency to learn or understand something. This relates to potential mental ability.
• Memory: The faculty by which the mind stores and remembers information. This is a cognitive function.

Identifying the Commonality and the Difference

Upon examining the meanings, we can see a pattern:

• Intelligence relates to mental capability.
• Aptitude relates to mental capability (potential).
• Memory relates to mental capability (cognitive function).
• Weight relates to a physical property or measurement.

Intelligence, Aptitude, and Memory are all concepts related to the mind, cognitive functions, or mental abilities. They describe aspects of intellectual or mental capacity. Weight, on the other hand, is a physical attribute that is measured and relates to mass and gravity, not mental processes.

Selecting the Different Word

Based on this analysis, the three words Intelligence, Aptitude, and Memory are alike because they describe mental attributes or capacities. The word Weight is different because it describes a physical attribute. Therefore, Weight is the word that does not belong to the group.

Conclusion on the Different Word

The word that is different from Intelligence, Weight, Aptitude, and Memory is Weight.

Additional Information: Understanding Mental vs. Physical Attributes

When grouping words, it's common to categorize them based on whether they describe physical properties, mental states, abstract concepts, actions, etc. In this question:

• Mental/Cognitive Attributes: These relate to the mind, thinking, learning, and understanding. Intelligence, Aptitude, and Memory fall into this category. They are not directly observable or measurable in the same way as physical properties.
• Physical Attributes: These relate to the tangible characteristics of objects or beings that can often be measured. Weight, height, temperature, and colour are examples of physical attributes. Weight is a specific physical measurement.

Recognizing these categories helps in identifying the word that is different in such analogy or classification questions.
