Cause–effect analogy: “Thunder is to Lightning as Grape is to ______”. Choose the option that stands to “Grape” as thunder stands to lightning.

Introduction / Context:
This analogy links a phenomenon to its cause or to the process that produces it, and then applies a similar pattern to an agricultural product. Thunder and lightning occur together in storms, but one is a result of the other. Grapes are fruits that can be processed into a widely known product. The question tests whether you understand both pairs as examples of effect or product arising from a cause or source.

Given Data / Assumptions:

• First pair: Thunder and Lightning. • Second given word: Grape. • Options: Wine, Soil, Seed, Water. • We assume standard school level understanding that lightning is a powerful electrical discharge in the atmosphere and that thunder is the sound produced as a result.

Concept / Approach:
Lightning is the flash of electricity in the sky during a storm. Thunder is the sound created by the rapid expansion of air caused by lightning. In simple terms, lightning is the cause and thunder is the effect. Similarly, grapes are the raw material or source fruit used to produce wine through fermentation. So grape stands to wine as lightning stands to thunder if we focus on the idea of “source or cause” and “product or effect”. The correct option for the second pair must be a well known product made from grapes, which is wine.

Step-by-Step Solution:
Step 1: Understand “Thunder : Lightning”. Although people often say “thunder and lightning” together, scientifically lightning comes first and creates the conditions that produce thunder. Thus, thunder is the result of lightning. Step 2: Apply the pattern to grapes. Grapes are not only eaten as fruit but also processed to produce wine. Wine is an alcoholic beverage made by fermenting the juice of grapes. Step 3: Check each option. Wine is a direct processed product of grapes. Soil is the medium in which grapevines grow, not the product of grapes. Seed is a part inside the grape, not the outcome produced from grapes. Water is used in irrigation and present in grapes but is not a derived product in the same sense. Step 4: The only option that clearly stands as a product produced from grapes, just as thunder is a result of lightning, is wine.

Verification / Alternative check:
We can phrase both relationships as “effect of a cause” or “product from a source”. Thunder is the audible effect of lightning. Wine is the processed product of grapes. Soil, seed, and water all relate to grapes in some way, but not in the same product relationship. They are either inputs or components of the growing process rather than outputs made from grapes. This confirms wine as the correct analogy partner.

Why Other Options Are Wrong:
• Soil: Necessary for growing grapevines but not something produced by grapes. • Seed: A part of the grape, not a product that grapes give rise to in the world. • Water: Involved in the life of the plant and present in the fruit but not the specific product of grapes in the way wine is.

Common Pitfalls:
Some learners may misinterpret the first pair and think of thunder and lightning as simply things that happen together, without noting the cause–effect direction. Another mistake is to pick soil or water because they relate to plants in general but ignore that the first pair is not about environment; it is about what one phenomenon produces. Matching that pattern carefully leads directly to grapes producing wine.

Final Answer:
The correct word that completes the analogy is Wine.
