Wrong options:

• hanging: The term 'hanging' does not relate to definitions and implies something suspended, which does not fit the context.
• using: While 'using' suggests application, it does not convey the sense of a definition being functional or practical as 'working' does.
• applying: 'Applying' implies putting something into action, which does not directly describe the nature of the definition being discussed.

Correct answer: distinctions

Explanation: The word 'distinctions' is appropriate as it refers to differences or variations that arise from the definition provided. It fits contextually as the author is highlighting subtle differences that may not be immediately clear.

Meaning: 'Distinctions' means differences or variations, indicating that the definition leads to an understanding of different aspects of drama.

Wrong options:

• implementations: 'Implementations' refers to the act of putting something into effect, which does not align with the context of discussing differences in definitions.
• distributions: 'Distributions' relates to the way something is shared or spread out, which is not relevant to the context of defining drama.
• comprehensions: 'Comprehensions' refers to understanding, which does not fit the context of identifying differences that arise from the definition.

Correct answer: open

Explanation: The word 'open' fits grammatically and contextually as it suggests the possibility of various interpretations or roles. It aligns with the idea that the definition allows for multiple understandings.

Meaning: 'Open' means allowing for possibilities or interpretations, indicating that the roles can be viewed in different ways.

Wrong options:

• go: 'Go' does not fit grammatically or contextually, as it does not convey the idea of possibility in relation to roles.

• undoubted: 'Undoubted' suggests certainty, which does not align with the context of allowing for various interpretations.

Meaning: 'Unnecessary' means not needed or superfluous, suggesting that the interaction may not seem essential but is actually significant.

Wrong options:

• uneven: 'Uneven' implies a lack of balance, which does not relate to the context of the importance of interaction.
• unabated: 'Unabated' means not diminishing, which does not fit the context of questioning the necessity of interaction.
• uncaring: 'Uncaring' suggests a lack of concern, which does not relate to the discussion of the importance of interaction in performances.

Correct answer: nevertheless

Explanation: The word 'nevertheless' serves as a discourse marker that contrasts the previous statement about characters appearing without interaction. It fits logically and contextually to emphasize the importance of interaction despite the previous point.

Meaning: 'Nevertheless' means in spite of that or nonetheless, indicating that despite the lack of interaction, it remains an important aspect of drama.

Wrong options:

• accordingly: 'Accordingly' implies a consequence or result, which does not fit the context of contrasting the previous statement.
• timely: 'Timely' refers to something done at the right moment, which does not relate to the context of interaction in performances.
• subsequently: 'Subsequently' indicates a following action, which does not fit the context of contrasting the importance of interaction.
