In the following sentence, a blank has been left for a describing word. Choose the alternative that best completes the sentence in meaning and grammar: He was too _____ to make a statement before the boss.

Introduction / Context:
This question checks whether you can select the most appropriate adjective to describe a person who does not dare to speak before a superior. The phrase “too _____ to make a statement before the boss” suggests fear, lack of courage, or nervousness, not simply physical tiredness or any random quality.

Given Data / Assumptions:

• Sentence: “He was too _____ to make a statement before the boss.”
• Options: shy, tired, timid, coward.
• The structure “too + adjective + to + verb” requires a proper adjective after too.
• The boss is a person in authority, so the situation can be intimidating.

Concept / Approach:
Timid is an adjective meaning shy, lacking in courage or confidence. It is used especially when someone hesitates to speak or act in front of others. Shy is similar, but timid is stronger and more suitable in a formal sentence describing fear of the boss. Tired describes physical or mental fatigue and does not explain fear of speaking. Coward is a noun, not an adjective, so it does not fit the grammatical pattern after “too”.

Step-by-Step Solution:
Recognise the structure: “too … to …” needs an adjective, not a noun.Eliminate coward because it is a noun; the correct form would be cowardly as an adjective.Consider tired: being tired might stop someone from working, but it does not naturally explain fear of speaking to the boss.Compare shy and timid: both mean lacking confidence, but timid more strongly conveys fearfulness or nervousness about speaking.Therefore, “too timid to make a statement before the boss” is the best match.

Verification / Alternative check:
Read the full sentence with each option: “too tired to make a statement” suggests simple exhaustion, not fear. “Too shy to make a statement” is possible but slightly weaker than timid; exams often prefer the more precise word. “Too timid to make a statement” is commonly used for people who are afraid to speak up. This choice captures both lack of courage and the formal tone of the sentence.

Why Other Options Are Wrong:
Shy is close in meaning but milder; a shy person may speak softly but can still talk when needed. The sentence emphasises an inability to speak, which timid captures more strongly. Tired refers to fatigue, not fear. Coward is grammatically incorrect in this slot and also describes a general character trait, not necessarily a momentary reluctance in one situation.

Common Pitfalls:
Many learners focus only on meaning and ignore grammar. Always check whether the word form is appropriate for its position in the sentence. When you see “too … to …”, you should expect an adjective. Among adjectives that suggest fear of speaking before authority, timid is more accurate and exam friendly than shy in this context.

Final Answer:
The sentence is best completed as: “He was too timid to make a statement before the boss.”
