Modern is the opposite of Antiquated. In a similar antonym based analogy, Weak is opposite to which of the following words?

Introduction / Context:
This analogy question tests basic understanding of antonyms in English vocabulary. The pair Modern : Antiquated shows a clear opposite relationship. Modern refers to something current or up to date, while Antiquated means old fashioned or out of date. In the second pair, Weak is given and we must choose the word that stands in the same opposite relation. Such antonym based analogies are common in verbal ability tests and help assess a candidate s sense of word meanings and contrasts.

Given Data / Assumptions:

• Modern and Antiquated are antonyms; one means new and current, the other old and outdated.
• Weak is the first word in the second pair.
• The options provided are Strong, Fragile, Inadequate, and Puny.
• We assume standard dictionary meanings of these English adjectives.

Concept / Approach:
The structure of the analogy is A : B :: C : D, where A and B are opposites and C and D must also be opposites. Modern and Antiquated form an antonym pair based on time or style. For the second pair, we look for the word that is the semantic opposite of Weak. Weak indicates low strength, low power, or lack of physical or mental force. Strong is the direct opposite because it indicates great strength, power, or firmness. The other options may sometimes appear related to weakness but they do not represent the clear, general antonym.

Step-by-Step Solution:
Step 1: Identify the relationship in the first pair: Modern and Antiquated are opposites in meaning. Step 2: Conclude that the analogy is based on antonyms. Step 3: For the second pair, consider the word Weak and look for its direct opposite. Step 4: Recall that the natural everyday antonym of Weak is Strong. Step 5: Check the remaining options. Fragile means easily broken, Inadequate means not enough, and Puny means small or feeble. Although they suggest weakness, they are not the general opposite used in most contexts. Step 6: Select Strong as the correct answer, completing the pattern Weak : Strong.

Verification / Alternative check:
To verify, we can think of common collocations and usage. We often say strong body, strong mind, strong argument, and we use weak body, weak mind, weak argument as direct opposites. In basic vocabulary exercises, the pair taught is Weak and Strong. Words like Fragile and Puny are more specific and narrower. Fragile relates to ease of breaking, while Puny relates to small size and poor development. Inadequate refers to insufficiency, often in quantity or quality. None of these are as direct an antonym of Weak as Strong, which covers both physical and abstract strength. This confirms Strong as the correct option.

Why Other Options Are Wrong:
Fragile: Fragile means delicate and easily broken. It is related to the idea of weakness but is not the general all purpose opposite of Weak.
Inadequate: Inadequate means not sufficient or not up to the required standard. It refers to quantity or quality rather than strength versus weakness.
Puny: Puny means very small and weak, but it is actually closer in meaning to Weak rather than being its opposite, so it cannot complete the analogy.

Common Pitfalls:
Some candidates get distracted by words that merely suggest a negative quality and may mistakenly think that any negative word will serve as an antonym. However, analogies usually expect the most direct and widely accepted opposite. Another pitfall is to treat Puny as an opposite due to its strong emotional tone, but it actually intensifies the idea of weakness rather than reversing it. Keeping a clear sense of basic antonym pairs such as high and low, hot and cold, weak and strong will help avoid such errors.

Final Answer:
Modern is the opposite of Antiquated, and in the same way Weak is opposite to Strong, so Strong is the correct answer.
