Daguerre continued to experiment and made, it seems by , an important discovery: he had put an exposed photographic plate - this was, of course, before the age of film - in his chemical cupboard and some days later found that the latent image had developed. There was also a broken thermometer in the cupboard, and he assumed that the vapour from the mercury had caused it. This meant it was now possible to reduce the time the plate was exposed from eight hours to thirty minutes.
This produced an image. The next step was to fix it, which he managed to do in 1837. He called this new process the Daguerreotype, then advertised and looked for sponsors, but initially very few people were interested. The discovery was made in January 1839, but details of the process were not given until August the same year, the French government in the meantime having bought the rights to the process.

Correct answer: invention
Explanation: The term 'invention' is the most appropriate choice as it refers specifically to the creation of something new, which aligns with the context of photography's development. The other options do not convey the same meaning of creating something novel, which is essential in this context.
Meaning: 'Invention' refers to the act of creating something that has not existed before, particularly a new device or process.
Wrong options:
- creation: While 'creation' implies bringing something into existence, it is broader and less specific than 'invention' in this context.
- discovery: 'Discovery' suggests finding something that already exists rather than creating something new, which does not fit the context of photography's development.
- manufacture: 'Manufacture' refers to the process of making something, typically on a large scale, and does not capture the essence of creating a new concept or technology.
Correct answer: brought
Explanation: The verb 'brought' is the correct choice as it indicates the action of causing something to happen, which fits the context of gaining fame through his work. It is grammatically correct in the past tense and aligns with the subject's achievements.
Meaning: 'Brought' means to cause something to happen or to lead to a particular result, in this case, fame.
Wrong options:
- gave: 'Gave' implies providing something to someone, which does not fit the context of achieving fame through one's actions.
- won: 'Won' suggests earning something through competition, which does not accurately describe how Daguerre achieved fame.
- gained: 'Gained' implies acquiring something, but it lacks the direct causative sense that 'brought' conveys in this context.
Correct answer: interest
Explanation: The word 'interest' is the most fitting choice as it refers to a strong curiosity or engagement in a subject, which aligns with Daguerre's passion for photography. It is grammatically correct and contextually appropriate.
Meaning: 'Interest' refers to a feeling of wanting to know or learn about something, indicating Daguerre's enthusiasm for photography.
Wrong options:
- curiosity: While 'curiosity' is similar, it implies a desire to learn rather than a deeper engagement or passion, which 'interest' better captures in this context.
- desire: 'Desire' suggests a strong wish for something, but it does not convey the same level of engagement as 'interest' does in relation to photography.
- concern: 'Concern' implies worry or care about something, which does not fit the positive context of Daguerre's engagement with photography.
Correct answer: accident
Explanation: The term 'accident' is the correct choice as it indicates an unexpected event that led to an important discovery. It fits grammatically and contextually, highlighting the serendipitous nature of Daguerre's finding.
Meaning: 'Accident' refers to an unforeseen event or occurrence, particularly one that happens by chance.
Wrong options:
- mistake: 'Mistake' implies an error or fault, which does not accurately describe the nature of Daguerre's discovery as it was a fortunate occurrence rather than an error.
- default: 'Default' refers to a failure to fulfill an obligation or requirement, which does not fit the context of an unexpected discovery.
- purpose: 'Purpose' indicates an intention or aim, which contradicts the accidental nature of the discovery described.
Correct answer: public
Explanation: The word 'public' is the most suitable choice as it indicates that the discovery was made known to the general population. It fits grammatically and contextually, emphasizing the significance of the announcement.
Meaning: 'Public' refers to something that is open or accessible to all people, indicating that the discovery was shared widely.
Wrong options:
- open: 'Open' suggests accessibility but lacks the specific connotation of being shared with the general populace that 'public' conveys.
- general: 'General' implies something that is common or widespread, but it does not specifically indicate the act of making something known to the public.
- official: 'Official' refers to something sanctioned by authority, which does not capture the broader sense of public awareness that 'public' does.
