In the following vocabulary based sentence completion question, choose the correct word to fill the blank: Walt Disney failed many times, but learned the right lessons and therefore failure was not ______ for him.

Introduction / Context:
This sentence speaks about Walt Disney and his attitude toward failure. It mentions that he failed many times but learned the right lessons, suggesting that his response to failure was constructive rather than negative. The question asks you to select the noun or adjective that best completes the idea that failure did not hold him back emotionally.

Given Data / Assumptions:

• The sentence structure is "failure was not ______ for him".
• It states that he learned the right lessons from failure.
• The options are "frustrating", "celebration", "argument", and "connector".
• The word must describe what failure was not like in his experience.

Concept / Approach:
Because the sentence mentions learning the right lessons, it implies that failure did not discourage him deeply. "Frustrating" is an adjective that describes causing discouragement, annoyance, and discouraging emotions. Saying "failure was not frustrating for him" fits the context: he did not allow failure to break his spirit. The other options do not fit naturally. "Celebration" is a noun that would require an article and different structure, and it does not make sense to say "failure was not celebration". "Argument" and "connector" are unrelated to emotional responses to failure and therefore are semantically wrong.

Step-by-Step Solution:
Identify the implied message: Disney transformed failure into learning opportunities.Conclude that failure did not upset or discourage him too much.Check each option. "Frustrating" describes a negative emotional impact and is the most relevant adjective.Notice that the other options are nouns with unrelated meanings.Choose "frustrating" as it creates the natural phrase "failure was not frustrating for him".

Verification / Alternative check:
Insert "frustrating" into the sentence: "Walt Disney failed many times, but learned the right lessons and hence failure was not frustrating for him." This sentence clearly conveys that he remained motivated despite failures. None of the other options can be inserted without creating an unnatural or meaningless sentence, confirming that "frustrating" is the only appropriate choice.

Why Other Options Are Wrong:
Option B, "celebration", does not fit grammatically or logically in the pattern "was not celebration for him". We would normally say "was not a celebration", and even that does not make sense here. Option C, "argument", has no connection with the emotional effect of failure. Option D, "connector", is a technical or abstract term that does not describe feelings or attitudes at all.

Common Pitfalls:
Some students may overthink the sentence and try to invent complex interpretations for "argument" or "connector". However, the simplest reading is usually correct in such exam questions. Always match the part of speech and basic meaning with the structure around the blank. Here, only an adjective that describes failure emotionally will fit, and among the options, "frustrating" is the obvious match.

Final Answer:
The correct completion is frustrating, giving "failure was not frustrating for him".
