Astronomers studying the remote galaxy cluster SPT0346-52 observed an extraordinarily high rate of star formation, a phenomenon that puzzled the research team. The galaxy is producing stars at thousands of times the rate of our Milky Way; yet it lacks the typical signs of active galactic nuclei. Initially, the scientists suspected a hidden supermassive black hole was fueling this growth, however, subsequent observations showed that the intense starburst is instead driven by a massive cosmic collision. This finding challenges existing models of early galactic evolution and suggests that merger events play a more dominant role than previously assumed.

Which of the following choices best resolves the underlined portion of the passage?

The QWERTY Legacy

[1]
Walk into any modern office or open a laptop, and you will find the same arrangement of letters on the keyboard: Q, W, E, R, T, and Y in the top-left row. This layout, known as QWERTY, is so ubiquitous that it seems like a natural law of technology. However, its origins lie in the mechanical limitations of the nineteenth century rather than any modern ergonomic design.

[2]
In the 1870s, Christopher Latham Sholes, a newspaper editor and printer from Milwaukee, developed the first commercially successful typewriter. His early prototypes had keys arranged alphabetically, but this setup caused a major problem. When typists typed rapidly, the typebars—the metal arms holding the letters—would swing up and collide, jamming the machine. To solve this, Sholes rearranged the keyboard layout.

[3]
A common myth is that Sholes designed QWERTY to deliberately slow down typists. In reality, he positioned frequently used letter pairs, such as 'TH' or 'HE,' on opposite sides of the keyboard. This separation ensured that the typebars would not strike in rapid succession and jam. The layout was not meant to hinder typing speed, but rather to allow for a continuous, jam-free typing rhythm.

[4]
Despite the rise of electronic keyboards and alternative layouts like the Dvorak Simplified Keyboard, which places the most common letters on the home row to reduce finger movement, QWERTY remains the global standard. Path dependency—the tendency of users to stick with an established technology because it is too costly or difficult to retrain—has cemented QWERTY’s position, proving that history often triumphs over efficiency.

Suppose the writer’s goal had been to write an essay that explains the mechanical necessity that led to the QWERTY layout and argues for its replacement by more modern, efficient keyboard layouts. Based on the passage, is the statement that the writer successfully achieved this goal true or false?
