A musician and member of the Quechua of Peru, Renata Flores Rivera was eager to promote the Quechua language in her music, but she was ______blank speaking it. She met this challenge by asking her grandmother, a native speaker of Quechua, to help her pronounce words in her song lyrics and also by taking classes in the language.

The following text is from Charlotte Brontë’s 1847 novel Jane Eyre. Jane, the narrator, works as a governess at Thornfield Hall.

I went on with my day’s business tranquilly; but ever and anon vague suggestions kept wandering across my brain of reasons why I should quit Thornfield; and I kept involuntarily framing advertisements and pondering conjectures about new situations: these thoughts I did not think to check; they might germinate and bear fruit if they could.

During a 2014 archaeological dig in Spain, Vicente Lull and his team uncovered the skeleton of a woman from El Algar, an Early Bronze Age society, buried with valuable objects signaling a high position of power. This finding may persuade researchers who have argued that Bronze Age societies were ruled by men to ______blank that women may have also held leadership roles.

Historians Tiya Miles and Roy E. Finkenbine have both documented the assistance Indigenous peoples gave to Black freedom seekers leaving the South before the US Civil War. Much of the historical evidence of this help comes from Indigenous oral traditions and from autobiographies written by the freedom seekers. One such narrative is Jermain Loguen’s autobiography, which tells about how Neshnabé (Potawatomi) villagers offered him food, lodging, and directions during his 1835 journey from Tennessee to Canada.

The following text is from Bram Stoker’s 1897 novel Dracula. The narrator is being driven in a carriage through a remote region at night.

The baying of the wolves sounded nearer and nearer, as though they were closing round on us from every side. I grew dreadfully afraid, and the horses shared my fear. The driver, however, was not in the least disturbed; he kept turning his head to left and right, but I could not see anything through the darkness.

Former astronaut Ellen Ochoa says that although she doesn’t have a definite idea of when it might happen, she ______blank that humans will someday need to be able to live in other environments than those found on Earth. This conjecture informs her interest in future research missions to the moon.

Microbes are tiny organisms in the soil, water, and air all around us. They thrive even in very harsh conditions. That’s why Noah Fierer and colleagues were surprised when soil samples they collected from an extremely cold, dry area in Antarctica didn’t seem to contain any life. The finding doesn’t prove that there are no microbes in that area, but the team says it does suggest that the environment severely restricts microbes’ survival.

Text 2

Microbes are found in virtually every environment on Earth. So it’s unlikely they would be completely absent from Fierer’s team’s study site, no matter how extreme the environment is. There were probably so few organisms in the samples that current technology couldn’t detect them. But since a spoonful of typical soil elsewhere might contain billions of microbes, the presence of so few in the Antarctic soil samples would show how challenging the conditions are.

Public policy researcher Anthony Fowler studied the history of elections in Australia, a country that requires citizens to vote. Fowler argues that requiring citizens to vote leads to a significant increase in voters who would otherwise not have the time or motivation to vote. Thus, election results in countries that require citizens to vote better reflect the preferences of the country as a whole. 

Text 2

Governments in democratic countries function better when more people vote. However, forcing people to vote may have negative consequences. Shane P. Singh and Jason Roy studied what happens when a country requires its citizens to vote. They found that when people feel forced to vote, they tend to spend less time looking for information about their choices when voting. As a result, votes from these voters may not reflect their actual preferences.

The following text is from Joseph Conrad’s 1907 novel The Secret Agent: A Simple Tale. Mr. Verloc is navigating the London streets on his way to a meeting.

Before reaching Knightsbridge, Mr. Verloc took a turn to the left out of the busy main thoroughfare, uproarious with the traffic of swaying omnibuses and trotting vans, in the almost silent, swift flow of hansoms [horse-drawn carriages]. Under his hat, worn with a slight backward tilt, his hair had been carefully brushed into respectful sleekness; for his business was with an Embassy. And Mr. Verloc, steady like a rock—a soft kind of rock—marched now along a street which could with every propriety be described as private.

According to historian Vicki L. Ruiz, Mexican American women made crucial contributions to the labor movement during World War II. At the time, food processing companies entered into contracts to supply United States armed forces with canned goods. Increased production quotas conferred greater bargaining power on the companies’ employees, many of whom were Mexican American women: employees insisted on more favorable benefits, and employers, who were anxious to fulfill the contracts, complied. Thus, labor activism became a platform for Mexican American women to assert their agency.

In a study of the benefits of having free time, Marissa Sharif found that the reported sense of life satisfaction tended to plateau when participants had two hours of free time per day and actually began to fall when they had five hours of free time per day. After further research, Sharif concluded that this dip in life satisfaction mainly occurred when individuals spent all their free time unproductively, such as by watching TV or playing games.

Text 2

Psychologist James Maddux cautions against suggesting an ideal amount of free time. The human desire for both free time and productivity is universal, but Maddux asserts that individuals have unique needs for life satisfaction. Furthermore, he points out that there is no objective definition for what constitutes productivity; reading a book might be considered a productive activity by some, but idleness by others.

Particle physicists like Ayana Holloway Arce and Aida El-Khadra spend much of their time ______blank what is invisible to the naked eye: using sophisticated technology, they closely examine the behavior of subatomic particles, the smallest detectable parts of matter.

The Cretaceous-Paleogene (K-Pg) mass extinction event is usually attributed solely to an asteroid impact near Chicxulub, Mexico. Some scientists argue that volcanic activity was the true cause, as the K-Pg event occurred relatively early in a long period of eruption of the Deccan Traps range that initially produced huge amounts of climate-altering gases. These dissenters note that other mass extinctions have coincided with large volcanic eruptions, while only the K-Pg event lines up with an asteroid strike.

Text 2

In a 2020 study, Pincelli Hull and her colleagues analyzed ocean core samples and modeled climate changes around the K-Pg event. The team concluded that Deccan Traps gases did affect global conditions prior to the event, but that the climate returned to normal well before the extinctions began—extinctions that instead closely align with the Chicxulub impact.

The following text is adapted from George Eliot’s 1871–72 novel Middlemarch.

[Mr. Brooke] had travelled in his younger years, and was held in this part of the country to have contracted a too rambling habit of mind. Mr. Brooke’s conclusions were as difficult to predict as the weather.

Historians studying pre-Inca Peru have looked to ceramic vessels to understand daily life among the Moche people. These mold-made sculptures present plants, animals, and human faces in precise ways—vessels representing human faces are so detailed that scholars have interpreted facial markings to represent scars and other skin irregularities. Some historians have even used these objects to identify potential skin diseases that may have afflicted people at the time.

Text 2

Art historian and archaeologist Lisa Trever has argued that the interpretation of Moche “portrait” vessels as hyper-realistic portrayals of identifiable people may inadvertently disregard the creativity of the objects’ creators. Moche ceramic vessels, Trever argues, are artworks in which sculptors could free their imagination, using realistic objects and people around them as inspiration to explore more abstract concepts.
