The Industrial Revolution was one of the most consequential transformations in human history, unfolding primarily during the 18th to 19th centuries. It originated in Britain and, over several decades, diffused across continental Europe and North America. The shift from hand production to machine-based manufacturing fundamentally altered economies, societies, and landscapes. Agrarian communities that had relied on farming for generations were progressively replaced by industrial ones centered on factories, mines, and railways. When did the Industrial Revolution primarily occur according to the passage?
Correct Answer: C. 18th to 19th centuries
The passage places the Industrial Revolution from the 18th to 19th centuries. It began in Britain and gradually spread to other parts of Europe and North America, transforming societies from agrarian to industrial. Mastering this concept helps in solving grammar-based questions in competitive.
Several factors converged to make Britain the cradle of the Industrial Revolution. The country's extensive coal deposits and iron ore provided the raw materials essential for steam engines and machinery. Income from colonial trade supplied the capital needed to finance factories and infrastructure. An existing culture of practical invention, combined with a legal system that protected property rights and patent claims, encouraged entrepreneurs to develop and apply new technologies. As a result, the industrialization process began in Britain and only later spread to other nations. Which country is identified as the birthplace of the Industrial Revolution in the passage?
Correct Answer: C. Britain
The passage identifies Britain as the birthplace of the Industrial Revolution. Factors such as colonial resources, available capital, and technological innovation made Britain ideal for industrialization. Mastering this concept helps in solving grammar-based questions in competitive.
Among the many industries transformed during the Industrial Revolution, textile production was one of the first to undergo wholesale mechanization. A sequence of inventions—including the spinning jenny, the water frame, and ultimately the steam-powered loom—replaced the slow and laborious hand-spinning and hand-weaving that had characterized cloth making for centuries. Factory owners could now produce fabric at a fraction of the previous cost and in far greater quantities. The mechanization of textiles became a model that other industries subsequently followed. What was one of the first major industries to be mechanized according to the passage?
Correct Answer: C. Textiles
The correct answer is 'Textiles'. The passage highlights textile production as one of the first industries to be mechanized. Inventions like the spinning jenny and power loom revolutionized fabric production and increased output dramatically.
The Industrial Revolution triggered a dramatic redistribution of population across Britain and, eventually, across Europe and North America. As factory work concentrated in specific towns and cities, millions of people left the countryside in search of wages, leading to the rapid growth of cities and industrial centers. Places that had been modest market towns swelled into sprawling urban agglomerations within a single generation. This urbanization brought both opportunity and hardship, straining housing, sanitation, and governance in ways that reformers struggled to address. How did the Industrial Revolution affect urbanization according to the passage?
Correct Answer: C. It led to rapid growth of cities and industrial centers
The passage describes how the Industrial Revolution led to rapid urbanization as people migrated from rural areas to cities seeking employment in factories. This created new industrial centers and transformed the landscape. Mastering this concept helps in solving grammar-based questions in competitive.
While the Industrial Revolution created new wealth and expanded the range of goods available to consumers, its immediate social consequences for working people were often severe. Factory workers—including children as young as six or seven—labored for twelve to sixteen hours a day in cramped, poorly ventilated buildings, performing repetitive tasks at dangerous machinery. Wages were kept low by the constant availability of fresh migrants from rural areas, and workers had little legal recourse against dismissal or injury. These harsh conditions eventually galvanized trade union movements and prompted governments to introduce factory legislation limiting working hours and child labor. What was a significant social consequence of the Industrial Revolution mentioned in the passage?
Correct Answer: C. Poor working conditions and low wages for factory workers
The passage notes that the Industrial Revolution resulted in poor working conditions, long hours, and low wages for factory workers, including children. These conditions eventually led to labor movements and workplace reforms. Mastering this concept helps in solving grammar-based questions in competitive.
At the center of modern biology is a molecule called deoxyribonucleic acid, commonly known by its abbreviation DNA. This molecule resides in the nucleus of virtually every living cell and encodes the chemical instructions that govern the development, functioning, and reproduction of all known organisms. DNA is composed of smaller units called nucleotides, each consisting of a phosphate group, a five-carbon sugar called deoxyribose, and one of four nitrogen-containing bases. The precise sequence of these bases along the DNA strand constitutes the genetic code of an organism. What does DNA stand for according to the passage?
Correct Answer: A. Deoxyribonucleic acid
The passage identifies DNA as deoxyribonucleic acid. This molecule contains the genetic instructions for all living organisms and is composed of nucleotides with a sugar-phosphate backbone. Mastering this concept helps in solving grammar-based questions in competitive.
One of the most iconic discoveries of twentieth-century science was the elucidation of DNA's three-dimensional architecture. The molecule takes the form of a double helix—two long, complementary strands wound around a common axis in the manner of a twisted ladder. The outer framework of each strand is formed by alternating sugar and phosphate groups, while the rungs of the ladder consist of paired nitrogen bases that hold the two strands together through hydrogen bonds. This elegant double helix structure, determined by James Watson and Francis Crick in 1953, explains how genetic information can be copied and passed from cell to cell. What is the shape of a DNA molecule as described in the passage?
Correct Answer: C. Double helix
The passage describes DNA's characteristic double helix structure. This structure, discovered by Watson and Crick, consists of two complementary strands twisted around each other. Mastering this concept helps in solving grammar-based questions in competitive.
The genetic information stored in DNA is written in an alphabet of just four chemical bases: adenine, thymine, guanine, and cytosine, conventionally abbreviated A, T, G, and C respectively. The two strands of the double helix are held together because each base on one strand pairs exclusively with a specific partner on the other—adenine always pairs with thymine, and guanine always pairs with cytosine. This strict base-pairing rule ensures that when a cell divides and its DNA is copied, both daughter cells receive an accurate replica of the parent's genetic instructions. The precise order of the bases along the molecule determines every heritable characteristic of the organism. What are the four bases that make up DNA according to the passage?
Correct Answer: A. A, T, G, C
The passage lists the four DNA bases as adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair specifically: A with T and G with C, maintaining the DNA structure. Mastering this concept helps in solving grammar-based questions in competitive.
DNA performs a role in living cells that can be likened to a master blueprint stored in a central archive. Its primary function is to store the genetic information needed to build proteins and to transmit that information reliably from one generation of cells to the next. Every time a cell divides, the DNA is duplicated so that each new cell inherits a complete copy of the organism's genetic instructions. During protein synthesis, specific regions of the DNA are transcribed into messenger RNA, which then serves as a template for assembling amino acids into functional proteins. What is the primary function of DNA as explained in the passage?
Correct Answer: B. Storing and transmitting genetic information
The passage explains that DNA's primary function is to store and transmit genetic information. It acts as a biological blueprint containing instructions for building and maintaining living organisms. Mastering this concept helps in solving grammar-based questions in competitive.
Along each DNA molecule are thousands of discrete functional units called genes, each occupying a defined region of the strand. A gene is a segment of DNA that contains the coded instructions for producing a particular protein or carrying out a specific biological function, and it is through the action of these proteins that observable traits—such as eye color, blood type, or disease susceptibility—are expressed. Different organisms carry different versions, or alleles, of the same genes, which accounts for the variation seen within species. The total collection of genes in an organism's DNA constitutes its genome. According to the passage, what is the relationship between genes and DNA?
Correct Answer: B. Genes are segments of DNA that code for specific traits
The passage explains that genes are specific segments of DNA that code for particular proteins and traits. Each gene contains the instructions for producing a specific characteristic or function in an organism. Mastering this concept helps in solving grammar-based questions in competitive.
