People in parts of western Africa and southwestern Asia were the first to realize that the dark-silvery rocks poking out of the earth could be worked into tools and weapons, sometime around 1500 B.C., evidence shows. The metal was probably discovered there accident when some ore was dropped into a fire and cooled into wrought iron, historians think. The eureka moment didn't reach Europe for 500 years, traveling slowly north and west through Greece, Italy, central Europe and finally to the British Isles the spread of the famous Celtic tribes. The Celts diffused iron technology over much of the continent through warfare, where their victory was assured due to the strength of iron weapons. Perhaps not the most peaceful of cultural exchanges, but where the technology did travel, it caught on fast. Iron life a lot easier in those days, when just living to the age of 45 was a feat. By that time, much of Europe had settled into small village life, the soil with bronze and stone tools. Iron farming tools, such as sickles and plough tips, made the process more efficient and allowed farmers tougher soils, try new crops and have more time for other activities.

Result:

A.I. Explanation:

Correct answer: by
Explanation: The preposition 'by' indicates the means through which something occurs, fitting grammatically and contextually as it describes how the discovery of metal happened, aligning with the phrase 'by accident.'
Meaning: 'By' in this context means 'through the means of' or 'as a result of,' indicating that the discovery was unintentional.
Wrong options:
at: 'At' indicates a specific location or time, which does not fit the context of how the discovery occurred.
for: 'For' suggests purpose or benefit, which does not align with the accidental nature of the discovery.
in: 'In' typically refers to a location or condition, which does not convey the means of occurrence as required here.
Correct answer: another
Explanation: 'Another' indicates an additional quantity or instance, which is appropriate here as it refers to the 500 years that passed before the eureka moment reached Europe.
Meaning: 'Another' means 'one more' or 'an additional one,' emphasizing the time gap before the technology spread to Europe.
Wrong options:
few: 'Few' implies a small number, which does not accurately describe the significant time span of 500 years.
less: 'Less' is used for uncountable nouns and does not fit with the countable time period of years.
further: 'Further' suggests a greater distance or extent, which does not apply to the context of time elapsed.
Correct answer: with
Explanation: The preposition 'with' indicates accompaniment or association, fitting well as it describes how the spread of technology occurred alongside the movement of the Celtic tribes.
Meaning: 'With' means 'together with' or 'in association with,' highlighting the connection between the spread of technology and the Celtic tribes.
Wrong options:
along: 'Along' suggests a linear movement or direction, which does not accurately convey the relationship between the spread of technology and the tribes.
without: 'Without' indicates absence, which contradicts the idea that the spread of technology was linked to the Celtic tribes.
for: 'For' implies purpose or benefit, which does not fit the context of describing the relationship between two subjects.
Correct answer: made
Explanation: The verb 'made' indicates creation or transformation, fitting grammatically and contextually as it describes how iron contributed to improving life.
Meaning: 'Made' means 'to cause to become' or 'to create,' indicating that iron technology significantly improved daily life.
Wrong options:
caused: 'Caused' implies a trigger for an event, which does not fit the context of describing the role of iron in improving life.
became: 'Became' suggests a change of state, which does not accurately describe the function of iron in this context.
begot: 'Begot' is an archaic term meaning to produce or generate, which is less commonly used and does not fit the modern context of the sentence.
Correct answer: toiling
Explanation: The gerund 'toiling' indicates continuous effort or labor, fitting well as it describes the ongoing action of working the soil with tools.
Meaning: 'Toiling' means 'working hard' or 'laboring,' emphasizing the effort involved in farming during that time.
Wrong options:
having: 'Having' indicates possession, which does not convey the action of working the soil.
burdening: 'Burdening' implies causing a load or stress, which does not accurately describe the act of farming.
treading: 'Treading' suggests walking or stepping, which does not fit the context of actively working the soil.
Correct answer: to exploit
Explanation: The infinitive form 'to exploit' indicates purpose or intention, fitting grammatically as it describes the farmers' aim in using iron tools.
Meaning: 'To exploit' means 'to make full use of' or 'to utilize effectively,' indicating the farmers' intention to maximize their agricultural efforts.
Wrong options:
exploit: The base form 'exploit' does not fit grammatically in this context as it lacks the necessary infinitive form.
exploits: 'Exploits' is a third-person singular form, which does not match the intended subject of the sentence.
exploited: 'Exploited' is the past tense form, which does not convey the intended future action of the farmers.
