Understanding Sentence Completion and Word Choice

This question asks us to choose the most appropriate word to fill in the blank in the sentence: "The result of the prolonged discussion was _______". We need to understand the grammatical role of the missing word and the meaning of the options provided.

Analyzing the Sentence Structure

The sentence has the structure: Subject + Linking Verb + Complement.

• Subject: "The result of the prolonged discussion"
• Linking Verb: "was" (a form of the verb 'to be')
• Complement: The blank space needs a word that describes or identifies the subject.

When a linking verb like 'was' connects the subject to a word that describes it, that word is typically an adjective. If the word renames the subject, it's typically a noun or a noun phrase. In this context, the blank is likely describing the nature of the result.

Examining the Options

Let's look at the given options and their grammatical functions:

1. disappointment: This is a noun. A noun after a linking verb usually identifies or renames the subject (e.g., "He is a doctor"). In this sentence, "disappointment" is a feeling, and while the result might *cause* disappointment, the result itself isn't typically called "disappointment".
2. disappointing: This is the present participle of the verb 'disappoint', used here as an adjective. Adjectives describe nouns. "Disappointing" means causing disappointment. This word can describe the nature of the result. For example, "The movie was disappointing."
3. disappointed: This is the past participle of the verb 'disappoint', often used as an adjective to describe someone who feels disappointment (e.g., "He was disappointed"). It describes the state of feeling disappointed. The subject of our sentence is "the result", not a person who can feel disappointed.
4. to dissappoint: This is an infinitive phrase (the verb 'to disappoint' preceded by 'to'). Infinitives can function as nouns, adjectives, or adverbs, but spelling is incorrect ('dissappoint' should be 'disappoint'). Even with the correct spelling, an infinitive phrase doesn't fit naturally here to describe the quality of the result.

Determining the Correct Word

We need a word that describes the 'result' and functions as an adjective. Comparing the options, 'disappointing' is an adjective that describes something that causes disappointment. This fits the context perfectly – the result of the discussion caused disappointment, hence it was a disappointing result.

Let's consider the corrected sentence with the appropriate word:

"The result of the prolonged discussion was disappointing."

This sentence makes grammatical and logical sense. The result possessed the quality of being disappointing.

Conclusion

Based on the grammatical structure requiring an adjective to describe the subject ('The result'), and the meanings of the options, 'disappointing' is the only word that correctly functions as an adjective describing the nature of the result.

Revision Table: Understanding Participles as Adjectives

Participles (present and past) can often function as adjectives. It's important to distinguish between them:

In our sentence, the 'result' is something that *causes* disappointment, so the present participle 'disappointing' is appropriate.

Additional Information: Common Errors in Word Choice

Choosing between '-ing' and '-ed' adjectives derived from verbs (like interesting/interested, boring/bored, surprising/surprised, disappointing/disappointed) is a common area of difficulty. Remember:

• Use the '-ing' form (present participle) to describe the *thing or person that causes* the feeling.
• Use the '-ed' form (past participle) to describe the *person or animal that experiences* the feeling.

For example:

• The news was shocking. (The news caused shock)
• He was shocked by the news. (He felt shock)
• The movie was boring. (The movie caused boredom)
• They were bored during the movie. (They felt boredom)

Applying this rule helps in correctly choosing the word for sentence completion questions like this one.
