In the following question, out of the four alternatives, select the one-word substitute that best expresses the given phrase: The highest point.

Introduction / Context:
This one word substitution question asks you to choose a single word that means “the highest point”. Such words are often used in essays and reports to describe the peak of success, power or physical height. Knowing the correct term allows you to write and understand precise, vivid descriptions.

Given Data / Assumptions:

• Phrase: The highest point.
• Options: Tempest, utpost, Archive, Zenith.
• We must select the option that correctly matches this meaning.
• We assume standard dictionary meanings for these words.

Concept / Approach:
Zenith literally refers to the point in the sky directly above an observer and is commonly used metaphorically to mean the highest point or peak of something, such as “the zenith of his career.” Tempest means a violent storm. “Utpost” appears to be a misspelling of outpost, which refers to a small military station far from the main force. Archive refers to a collection of historical records. None of these except zenith correspond to the idea of a highest point.

Step-by-Step Solution:
Interpret the phrase “the highest point” literally and metaphorically as peak, summit or top.Option Tempest: a strong storm, not a point or position.Option “utpost”: likely meant to suggest outpost, a distant military or frontier station, not the highest point.Option Archive: storage of records or documents, unrelated to height.Option Zenith: established term for the highest point in the sky or the peak of achievement.Therefore, zenith is the correct one word substitute.

Verification / Alternative check:
Use zenith in an example: “At the zenith of the empire, its territory stretched across many continents.” Here, zenith clearly means the highest or most powerful stage. Similarly, “The sun reached its zenith at noon” uses the word in its original astronomical sense. None of the other options can replace zenith in these sentences without destroying the meaning.

Why Other Options Are Wrong:
Tempest relates to weather and means a violent storm. An outpost (here misspelt) is a defensive or advanced position, not a peak. Archive deals with storage of documents and is used in libraries, offices or digital storage, not to indicate a high point. None of them carries the notion of climax, peak or summit that “the highest point” requires.

Common Pitfalls:
Students sometimes get distracted by unfamiliar spellings like “utpost” and assume they hide the answer. However, in one word substitution questions, the correct option is usually a well known term that directly fits the definition. Remember that zenith and its counterpart nadir (lowest point) often appear together in advanced English. This helps you quickly choose zenith for “the highest point”.

Final Answer:
The one word substitute for “the highest point” is Zenith.
