Meaning: 'Exhibit' means to display or present something for public viewing, particularly in a formal setting.

Wrong options:

• show: 'Show' is a more general term and does not convey the formal context of a public display as effectively as 'exhibit.'
• feature: 'Feature' implies highlighting something but lacks the connotation of a formal presentation that 'exhibit' provides.
• demonstrate: 'Demonstrate' suggests showing how something works rather than presenting it for public viewing, making it less suitable here.

Correct answer: prolonged

Explanation: The word 'prolonged' fits grammatically as it describes the action of extending time, which is appropriate in the context of capturing movement in photography. It aligns with the past tense used in the sentence.

Meaning: 'Prolonged' means to extend the duration of something, indicating that the photographs captured the runner's movement over a longer time frame.

Wrong options:

• splash: 'Splash' refers to a sound or action of liquid and does not relate to the context of photography or movement.
• extended: 'Extended' is similar but does not convey the same sense of duration as 'prolonged' in this specific context.
• spread: 'Spread' implies a physical distribution rather than the temporal aspect of capturing movement, making it unsuitable here.

Correct answer: drop

Explanation: The word 'drop' fits grammatically as it indicates the action of letting something fall, which is relevant to the context of Edgerton's study of milk hitting a surface. It matches the past tense structure of the sentence.

Meaning: 'Drop' means to let something fall or descend, particularly in this context where it refers to milk falling onto a dish.

Wrong options:

• put: 'Put' implies placing something down but lacks the dynamic action associated with 'drop' in this context.
• dash: 'Dash' suggests a quick movement but does not accurately describe the action of milk hitting a surface.
• drip: 'Drip' refers to a slow fall of liquid, which does not convey the same impact as 'drop' in this scenario.

Correct answer: lot

Explanation: The word 'lot' fits grammatically as it refers to a quantity or amount, which is appropriate in the context of describing the amount of milk. It aligns with the noun form needed in this context.

Meaning: 'Lot' means a large quantity or amount of something, indicating that a significant volume of milk was involved in the experiment.

Wrong options:

• subject: 'Subject' refers to a person or thing being discussed or studied, which does not fit the context of measuring a quantity of milk.
• economic: 'Economic' relates to economics and does not pertain to the context of measuring milk.
• step: 'Step' refers to a movement or stage in a process, which does not relate to the quantity of milk being studied.

Correct answer: leave

Explanation: The word 'leave' fits grammatically as it indicates the action of departing from something, which is relevant in the context of sports photographers abandoning their cumbersome cameras. It matches the past tense structure of the sentence.

Meaning: 'Leave' means to go away from or abandon something, indicating that photographers could move on from using large cameras.

Wrong options:

• chose: 'Chose' is the past tense of 'choose' and does not fit the context of abandoning equipment.
• keep: 'Keep' implies retaining something, which contradicts the idea of leaving cumbersome cameras behind.
• lay: 'Lay' refers to placing something down and does not convey the action of abandoning equipment.

Correct answer: value

Explanation: The word 'value' fits grammatically as it indicates appreciation or importance, which is relevant in the context of how viewers perceive still images after watching sports on TV. It aligns with the present tense used in the sentence.

Meaning: 'Value' means to regard something as important or beneficial, indicating that viewers appreciate still images as reminders of the game.

Wrong options:

• highly: 'Highly' is an adverb and does not fit grammatically as a verb in this context.
• pointed: 'Pointed' is an adjective that does not convey the action of appreciating or recognizing importance.
• cheered: 'Cheered' implies vocal support or applause, which does not fit the context of valuing still images.
