Understanding the Group/Class for Lock, Block, Fasten

The question asks us to identify a word from the given options that belongs to the same group or class as "Lock", "Block", and "Fasten". Let's analyze the common characteristic of these three words.

• Lock: To secure something with a lock, preventing access or movement.
• Block: To obstruct movement or access; to prevent something from passing or happening.
• Fasten: To attach or join securely; to close or secure something firmly.

The words "Lock", "Block", and "Fasten" all describe actions that involve securing, preventing movement, obstructing access, or closing something firmly.

Analyzing the Options

Now, let's examine each option to see which one fits into this group.

1. Open: This word describes the opposite action of securing or closing. Opening something allows access or movement. This is contrary to the meaning of Lock, Block, and Fasten.
2. Window: This is an object, a part of a building or vehicle. While windows can be locked or blocked, the word itself doesn't represent the action of securing or preventing movement like Lock, Block, or Fasten do.
3. Shut: This word means to close something. When you shut a door or a window, you are closing off access or preventing it from being open. This action is often a preliminary step to locking or fastening, and it serves a similar purpose of closing off or securing an entry or passage.
4. Door: Similar to Window, a door is an object. It's a part of a building that can be locked, blocked, fastened, or shut, but the word "Door" itself is not an action related to securing or preventing movement.

Finding the Matching Alternative

Comparing the options with the characteristics of "Lock", "Block", and "Fasten", we see that "Shut" is the action that aligns most closely. Shutting something involves closing it off, which relates to the idea of securing or preventing access, much like locking, blocking, or fastening.

Conclusion

The alternative that can be a member of the given group/class (Lock, Block, Fasten) is Shut, as it represents an action of closing off or securing, similar in function to the other words in the group.

Revision Table: Group Members

Additional Information: Types of Actions

Words can be grouped based on their meaning, function, or the type of action they describe. In this case, the group includes verbs that describe actions related to closing, securing, or obstructing.

• Verbs like Lock, Block, and Fasten are used to describe making something secure or inaccessible.
• "Shut" is also a verb that describes closing something, often making it less accessible.
• Nouns like "Window" and "Door" represent physical objects.
• The verb "Open" is antonymous to the actions in the group.

Understanding the part of speech (verb, noun, etc.) and the core meaning of words helps in identifying members of a group or class.
