Passage 1
The discovery of penicillin by Alexander Fleming in 1928 is often regarded as one of the most significant medical breakthroughs of the 20th century. Fleming’s chance observation of a mold that killed bacteria laid the foundation for antibiotics, which have since saved millions of lives. Before penicillin, even minor infections could lead to serious illness or death. However, the journey from Fleming’s initial discovery to the mass production of penicillin was not straightforward. It required the collaborative efforts of scientists such as Howard Florey and Ernst Boris Chain, who developed methods to purify and produce penicillin on a large scale during World War II. Their work not only accelerated the availability of the drug but also revolutionized the treatment of bacterial infections, fundamentally altering the landscape of modern medicine.

- What is the primary focus of the passage?
(A) The dangers of fossil fuel dependency.
(B) The increasing adoption and impact of renewable energy.
(C) The economic consequences of climate change.
(D) The competition between solar and wind energy. - According to the passage, what has contributed to the growth of renewable energy?
(A) Increased demand for traditional power sources.
(B) Innovations in nuclear energy.
(C) A decrease in fossil fuel availability.
(D)Advances in technology and lower costs. - The author’s tone can best be described as:
(A) Pessimistic and doubtful.
(B) Analytical and optimistic.
(C) Neutral and indifferent.
(D) Critical and accusatory.
Passage 3:
The Industrial Revolution, which began in the late 18th century, marked a profound shift in manufacturing processes. Before this period, goods were primarily produced by hand, often in homes or small workshops. The advent of machinery, steam power, and factory-based production led to significant increases in efficiency and output. While the revolution spurred economic growth and urbanization, it also brought about social changes and challenges. Labor conditions in factories were often harsh, with long hours and minimal regulations. Despite these difficulties, the Industrial Revolution laid the groundwork for modern economies, transforming societies and reshaping global trade.
Questions:
- The passage primarily discusses:
(A) The role of artisans in pre-industrial society
(B) The daily life of factory workers.
(C)The invention of the steam engine.
(D)The impact and significance of the Industrial Revolution. - What was one consequence of the Industrial Revolution mentioned in the passage?
(A) A decline in agricultural production.
(B) An increase in hand-made goods.
(C) Economic growth and urbanization.
(D) A return to traditional methods of production. -
The author’s tone can best be described as:
(A) Neutral and factual.
(B) Nostalgic and sentimental.
