The passage recalls Emerson view that the poet imagination makes him master of land, sea, and air, and then notes that what poets dream one day often becomes a technological reality for everyone, such as flight into outer space, which even early aeroplane inventors could hardly have imagined. On the basis of this passage, which of the following statements is best supported?

Introduction / Context:
This theme detection question connects poetry, imagination, and technological achievement. The passage mentions Emerson description of the poet as landlord, sealord, and airlord, whose imagination makes him master of land, sea, and air. It then observes that poet dreams of yesterday often become the practical achievements of today for all people, citing flight into outer space as an example that even the pioneers of aeroplanes might not have foreseen. We must determine which statement best reflects the central idea of imagination leading to real world achievement.

Given Data / Assumptions:

• Poets use imagination to conquer land, sea, and air in a figurative way.
• Ideas that begin as poetic dreams can later turn into concrete technological achievements.
• Flight into outer space is an example of something that was once beyond imagination for early aeroplane inventors.
• The passage suggests a link between imagination and later practical realisation but does not say that every single imagination becomes reality.
• It also does not claim that outer space exploration is the final limit of technology.

Concept / Approach:
We look for the answer option that summarises this relationship between imagination and reality without exaggerating it. Statements that say all imaginations become reality overstate the point. Similarly, claims that human technological development has reached a final climax are not supported by the passage. The correct statement will acknowledge that many imagined possibilities have later been realised through ideas and hard work, without making universal or final claims.

Step-by-Step Solution:
Step 1: Examine option b. It says that what humans imagine is often not impossible and that through ideas and hard work they frequently transform such imaginations into reality. This captures both the role of imagination and the necessary effort.Step 2: Compare with the passage. The text explicitly says that a poet dream of yesterday becomes an actual achievement and reality for all, and it illustrates this with flight into outer space. This supports the idea that imagination and subsequent work can lead to major achievements.Step 3: Evaluate option a. It claims all imaginations become reality some day. The passage never suggests this universal statement; it only gives examples where imagination preceded achievement.Step 4: Evaluate option c. It narrows the idea to poetry and suggests that only seemingly impossible imaginations make a good poet. The passage does not evaluate what makes a good poet; it focuses on the general link between imagination and future reality.Step 5: Evaluate option d. It states that outer space exploration is the climax of technological development, a claim not made or implied by the text.Step 6: Since option b aligns with the passage and the others do not, option e is also incorrect.

Verification / Alternative check:
Paraphrase the passage in simple language: Poets imagine grand possibilities, and over time, some of these imaginative visions become real technologies, such as human flight and space travel. This is very close to the idea that many human imaginations are not impossible; with effort and innovation, humans often convert them into reality. Option b states exactly that. Options a and d overstate the case either by claiming universality or finality, which the passage carefully avoids.

Why Other Options Are Wrong:

• Option a stretches the idea to all imaginations, which is not supported.
• Option c changes the focus from imagination becoming reality to a criterion for being a good poet, which the passage does not discuss.
• Option d introduces a new claim about the final climax of technology that is absent from the passage.
• Option e is wrong because option b fits the passage well.

Common Pitfalls:
A common error is to choose options that sound inspirational but go beyond what the text actually says. Another pitfall is treating a specific example, such as space travel, as if it were a claim about the ultimate limit of development. Reading carefully shows that the passage highlights the power of imagination combined with human effort, not universal success of every imagined idea or a final endpoint of technology.

Final Answer:
What humans imagine is often not impossible, and through ideas and hard work they frequently transform such imaginations into reality.
