Understanding Sentence Structure and Phrase Substitution

The question asks us to find the most appropriate option to replace the underlined segment "out" in the sentence: "The rate of interest for the loan went out all our calculations." We need to evaluate each option to see which one creates a grammatically correct and meaningful sentence in the context of interest rates and calculations.

Analyzing the Original Sentence Segment

The phrase "went out all our calculations" is not a standard English idiom or construction. When something exceeds or surpasses a limit, expectation, or calculation, different prepositions or adverbs are typically used.

Evaluating the Substitution Options

Let's look at each option provided:

• Option 1: under all our calculations
  Substituting "out" with "under" would give: "The rate of interest for the loan went under all our calculations." The phrase "went under" usually means failed or collapsed, or literally moved underneath something. In the context of calculations, "under calculations" would imply a rate lower than calculated. This does not fit the likely intended meaning of a rate exceeding expectations, and "went under all our calculations" is not a standard phrase.
• Option 2: No substitution
  The original sentence with "went out all our calculations" is grammatically incorrect and lacks clear meaning in this context. Therefore, a substitution is necessary.
• Option 3: beyond all our calculations
  Substituting "out" with "beyond" would give: "The rate of interest for the loan went beyond all our calculations." The phrase "went beyond" is a common idiom that means to exceed or surpass something. "Beyond calculations" means more than what was calculated or expected. This fits the context perfectly, implying the interest rate was higher than anticipated based on the calculations.
• Option 4: besides all our calculations
  Substituting "out" with "besides" would give: "The rate of interest for the loan went besides all our calculations." "Besides" means in addition to or apart from. "Went besides" is not a standard phrase in this context. It doesn't convey the meaning of exceeding calculations.

Identifying the Correct Substitution

Based on the analysis, the phrase "beyond all our calculations" is the only option that correctly completes the sentence and conveys the intended meaning that the interest rate exceeded what was calculated. The correct sentence should be: "The rate of interest for the loan went beyond all our calculations."

Therefore, the most appropriate option to substitute the underlined segment is "beyond all our calculations".
