Understanding the Phrase Substitution Question

The question asks us to find the best substitute for the phrase: "Involving many carefully arranged parts or details; detailed and complicated in design and planning." We need to examine the meaning of each given option and see which one most accurately captures the essence of this description.

Analyzing the Options

Let's look at the meaning of each alternative provided:

1. Labyrinthine: This word describes something that resembles a labyrinth or maze; it is intricate, confusing, and often difficult to find one's way through. While it implies complexity, it often carries a connotation of bewilderment or being difficult to navigate, more than just careful arrangement.
2. Facile: This means appearing easily achieved, effortless, or superficial. It can also describe a person who is fluent but lacks depth or sincerity. This meaning is directly opposite to the idea of being "detailed and complicated."
3. Elaborate: This word means involving many carefully arranged parts or details; intricate and complex in design and planning. It fits the description of something that is worked out with great care and attention to detail.
4. Prodigious: This means remarkably or impressively great in extent, size, or degree. It relates to magnitude or quantity, not necessarily the intricacy of design or planning. For example, a prodigious talent means great talent, or a prodigious amount means a very large amount.

Finding the Best Substitute Word

Now let's compare the meanings of the options with the given phrase:

• The phrase describes something that is "detailed and complicated in design and planning" and involves "many carefully arranged parts or details."
• Labyrinthine implies complexity but focuses more on being like a maze, often confusing.
• Facile is the opposite, meaning simple or superficial.
• Prodigious relates to size or degree, not complexity of structure.
• Elaborate perfectly matches the description of having many carefully arranged parts, being detailed, and complicated in design and planning.

Therefore, elaborate is the best substitute for the given phrase.

Detailed Explanation of the Best Fit: Elaborate

When we describe something as elaborate, we mean that it is complex and detailed, often because a lot of effort has been put into its creation or planning. An elaborate plan has many steps and contingencies. An elaborate design has many intricate parts and details. This aligns precisely with the phrase "involving many carefully arranged parts or details; detailed and complicated in design and planning."

Consider these examples:

• An elaborate wedding ceremony involves detailed planning for guests, decorations, timings, and rituals.
• An elaborate machine has many complex, carefully arranged components that work together.

Both examples fit the idea of something being detailed and complicated due to careful arrangement and planning.

Conclusion on Phrase Substitution

Based on the analysis of each option's meaning, the word that best substitutes the phrase "Involving many carefully arranged parts or details; detailed and complicated in design and planning" is elaborate.
