Meaning: 'Attracted' means to draw or pull in, especially in the context of gaining interest or attention from people.

Wrong options:

• forced: The word 'forced' implies coercion, which does not fit the context of inviting a public to watch films.
• told: The word 'told' suggests communication of information, which does not convey the action of drawing in an audience.
• liked: The word 'liked' indicates preference, which is not relevant to the action of bringing in a public audience.

Correct answer: blossom

Explanation: The word 'blossom' is used here to indicate growth or development over time, fitting grammatically and contextually as it describes how the commercial aspect of cinema evolved.

Meaning: 'Blossom' means to develop or flourish, often used metaphorically to describe something that grows positively.

Wrong options:

• convert: The word 'convert' implies a change in form or function, which does not accurately describe the growth of cinema as a commercial entity.
• popular: The word 'popular' is an adjective and does not fit grammatically as a verb in this context.
• leap: The word 'leap' suggests a sudden movement or change, which does not align with the gradual development implied by 'blossom.'

Correct answer: industry

Explanation: The word 'industry' is a noun that correctly identifies the sector of cinema as a whole, fitting grammatically and contextually within the sentence structure.

Meaning: 'Industry' refers to the economic activity concerned with the processing of raw materials and the manufacture of goods, in this case, films.

Wrong options:

• industries: The plural form 'industries' does not fit as the sentence refers to cinema as a singular entity.
• industrialization: The term 'industrialization' refers to the process of developing industries, which does not fit the context of describing the cinema itself.
• industrialized: The word 'industrialized' is an adjective that describes a state of being and does not fit grammatically as a noun in this context.

Correct answer: had to listen

Explanation: The phrase 'had to listen' fits grammatically as it indicates a necessity in the past, aligning with the context of audiences experiencing films without sound.

Meaning: 'Had to listen' means that audiences were required to pay attention to sounds, even though there was no spoken dialogue in the films.

Wrong options:

• hear: The word 'hear' is in the present tense and does not fit the past context of the sentence.
• see: The word 'see' does not convey the auditory experience that is being described in relation to silent films.
• had to view: The phrase 'had to view' is redundant since viewing is already implied in the context of watching films.

Correct answer: In fact

Explanation: The phrase 'In fact' serves as a discourse marker that introduces a clarification or contradiction to the previous statement, fitting well grammatically and contextually.

Wrong options:

• Usually: The word 'Usually' implies a common occurrence, which does not fit the context of providing a specific clarification.
• Curious: The word 'Curious' does not logically connect to the preceding statement and does not serve as a transition.
• To understand: The phrase 'To understand' suggests a purpose rather than providing a clarification, making it unsuitable here.

Correct answer: dialogue

Explanation: The word 'dialogue' fits grammatically as a noun that refers to spoken exchanges between characters, which is absent in silent films, aligning with the context of the sentence.
