Understanding the Passage and Fill-in-the-Blank Question

The question asks us to complete a passage by selecting the most appropriate word for the first blank from the given alternatives. We need to read the passage carefully and understand the context to choose the word that makes the sentence grammatically correct and logically sound.

The passage is:

"It so happens that ______ siblings sing, one of ______ invariably has a less ______ vocal prowess even though ______ have a similarly commendable ______ base."

We are focusing on filling the first blank.

Analyzing the First Blank

The first blank is followed by the phrase "siblings sing". This phrase describes an action or a situation. The blank needs a word that connects "It so happens that" with the situation "siblings sing". This connecting word should introduce the context or the condition under which the subsequent part of the sentence ("one of ______ invariably has a less ______ vocal prowess...") occurs.

Evaluating the Options

Let's examine each option provided for the first blank:

• Option 1: how - "It so happens that how siblings sing..." This phrasing focuses on the manner or method of singing. While grammatically possible in some structures, it doesn't fit naturally to introduce the situation itself following "It so happens that".
• Option 2: when - "It so happens that when siblings sing..." This introduces the situation by indicating the time or occasion during which siblings sing. "It so happens that when X happens, Y occurs" is a common and grammatically correct structure used to describe a recurring event or observation. This fits well with the idea that something "invariably" happens when siblings sing.
• Option 3: if - "It so happens that if siblings sing..." This introduces a condition. While "if" introduces a condition, "when" is generally preferred when describing a recurring or typical situation that is observed to happen, especially following a phrase like "It so happens that". The subsequent use of "invariably" suggests we are describing what always happens in a specific situation, making "when" a better fit than "if" which implies a potential but not guaranteed condition.
• Option 4: they - "It so happens that they siblings sing..." "They" is a pronoun and cannot function as a conjunction to introduce the clause "siblings sing" in this structure. This option is grammatically incorrect.

Determining the Correct Word

Based on the analysis, the word "when" is the most suitable choice for the first blank. It correctly introduces the situation or the time frame (when siblings are singing) during which the subsequent part of the sentence (something invariably happens regarding vocal prowess) occurs. The phrase "It so happens that when..." is a standard construction to describe a typical or observed occurrence.

The completed first part of the sentence reads: "It so happens that when siblings sing..."

Additional Information on Sentence Completion

Sentence completion questions require careful reading and understanding of the entire sentence or passage. Consider the following steps:

• Read the sentence/passage with the blank(s).
• Try to predict a word that fits the context.
• Examine the options provided.
• Test each option in the blank to see if it makes sense grammatically and contextually.
• Look for clues in the surrounding words and sentences (like "it so happens that" and "invariably" in this case) that indicate the type of word needed (e.g., time, condition, cause, effect).
• Eliminate options that are clearly incorrect based on grammar or meaning.
• Choose the option that fits best in terms of meaning, grammar, and flow.

Understanding different types of conjunctions and how they connect ideas is crucial for excelling in such questions.
