Renewable energy sources, such as solar and wind power, are becoming increasingly important in the fight against climate changeThese technologies help reduce reliance on fossil fuels and decrease greenhouse gas emissionsHowever, their intermittent nature and high initial costs can be obstacles to widespread adoption.
Question: 1
What is one obstacle to widespread adoption of renewable energy mentioned in the passage?
What is one obstacle to widespread adoption of renewable energy mentioned in the passage?
Show Hint
When a question asks about obstacles or challenges, scan the passage for contrast words like "however" or "but" — these often introduce the drawbacks after listing benefits

- Intermittent energy production
- Lower initial costs
- Reduced reliance on fossil fuels

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The question asks us to identify an *obstacle* to the widespread use of renewable energy, based on the passageLet’s break down the passage’s key points
It highlights benefits of renewable energy, such as
Reduced reliance on fossil fuels
Decreased greenhouse gas emissions
Then, it mentions two challenges
Intermittent nature of renewable energy
High initial costs
The term *intermittent* refers to the fact that solar and wind energy are not always available — the sun doesn't shine at night, and the wind doesn't always blowThis inconsistency can make it harder to rely solely on these sources, especially without effective energy storage systems Now, let’s evaluate each option
(A) Decreased greenhouse gas emissions — This is a benefit, not an obstacle
(B) Intermittent energy production — This is directly stated in the passage as an obstacle
(C) Lower initial costs — This contradicts the passage, which says the initial costs are *high*
(D) Reduced reliance on fossil fuels — Again, this is a benefit, not a problem
Therefore, the correct answer is (B) Intermittent energy production, as it matches one of the clearly stated obstacles

- In the 1970s, two debates engaged many scholars of early United States history. One focused on the status of women, primarily White women. Turning on the so-called golden age theory, which posited that during the eighteenth-century colonial era, American women enjoyed a brief period of high status relative to their English contemporaries and to nineteenth-century American women, this debate pitted scholars who believed women’s lives deteriorated after 1800 against those who thought women’s lives had been no better before 1800. At issue were the causes of women’s subordination: were these causes already in place when the English first settled North America or did they emerge with the rise of nineteenth-century industrial capitalism?
The second debate, the so-called origins debate, concerned the emergence of racial slavery in the southern colonies: was slavery the inevitable result of the deep-rooted racial prejudice of early British colonists or did racial prejudice arise only after these planters instituted slave labor?
Although these debates are parallel in some respects, key differences distinguished them. Whereas the debate over women’s status revolved around implicit comparisons of colonial women to their counterparts in the antebellum period (1800--1860), thus inviting comment from scholars of both historical periods, the origins debate was primarily confined to a discussion about slavery in colonial America. Second, in contrast to the newness of the debate over women’s status and its continued currency throughout the early 1980s, the debate over race and slavery, begun in the 1950s, had lost some of its urgency with the publication of Morgan’s American Slavery, American Freedom (1975), widely regarded as the last word on the subject.
Each debate also assumed a different relationship to the groups whose histories it concerned. In its heyday, the origins debate focused mainly on White attitudes toward Africans rather than on Africans themselves. With few exceptions, such as Wood’s Black Majority (1974) and Mullin’s Flight and Rebellion (1972), which were centrally concerned with enslaved African men, most works pertaining to the origins debate focused on the White architects, mostly male, of racial slavery. In contrast, although women’s historians were interested in the institutions and ideologies contributing to women’s subordination, they were equally concerned with documenting women’s experiences. As in the origins debate, however, early scholarship on colonial women defined its historical constituency narrowly, women’s historians focusing mainly on affluent White women.
Over time, however, some initial differences between the approaches taken by scholars in the two fields faded. In the 1980s, historians of race and slavery in colonial America shifted their attention to enslaved people; interest in African American culture grew, thereby bringing enslaved women more prominently into view. Historians of early American women moved in similar directions during the decade and began to consider the effect of racial difference on women’s experience.- GRE - 2025

- The most plausible justification for higher taxes on automobile fuel is that fuel consumption harms the environment and thus adds to the costs of traffic congestion. But the fact that burning fuel creates these “negative externalities” does not imply that no tax on fuel could ever be too high. Economics is precise about the tax that should, in principle, be levied to deal with negative externalities:
the tax on a liter of fuel should be equal to the harm caused by using a liter of fuel.
If the tax is more than that, its costs (including the inconvenience to those who would rather have used their cars) will exceed its benefits (including any reduction in congestion and pollution).- GRE - 2025

- Objectively, of course, the various ecosystems that sustain life on the planet proceed independently of human agency, just as they operated before the hectic ascendancy of Homo sapiens. But it is also true that it is difficult to think of a single such system that has not, for better or worse, been substantially modified by human culture. Nor is this simply the work of the industrial centuries. It has been happening since the days of ancient Mesopotamia. It is coeval with the origins of writing, and has occurred throughout our social existence. And it is this irreversibly modified world, from the polar caps to the equatorial forests, that is all the nature we have.

- The following appeared in a health newsletter.
"Nosinia is an herb that many users report to be as effective as prescription medications at fighting allergy symptoms. Researchers recently compared Nosinia to a placebo in 95 men and women with seasonal allergies to ragweed pollen. Participants in the study reported that neither Nosinia nor the placebo offered significant relief. However, for the most severe allergy symptoms, the researchers reported that Nosinia was more effective than the placebo in providing relief. Furthermore, at the end of the study, participants given Nosinia were more likely than participants given a placebo to report feeling healthier. We, therefore, recommend using Nosinia to help with your severe allergy symptoms."- GRE - 2025

- The following appeared in a memorandum from the manager of WWAC radio station.
“To reverse a decline in listener numbers, our owners have decided that WWAC must change from its current rock-music format. The decline has occurred despite population growth in our listening area, but that growth has resulted mainly from people moving here after their retirement. We must make listeners of these new residents. We could try playing music tailored to their tastes, but a continuing decline in local sales of recorded music suggests limited interest in music. Instead, we should change to a news and talk format, a form of radio that is increasingly popular in our area.”

- The following appeared as a letter to the editor from the owner of a skate shop in Central Plaza.
"Two years ago the city council voted to prohibit skateboarding in Central Plaza. They claimed that skateboard users were responsible for litter and vandalism that were keeping other visitors from coming to the plaza. In the past two years, however, there has been only a small increase in the number of visitors to Central Plaza, and litter and vandalism are still problematic. Skateboarding is permitted in Monroe Park, however, and there is no problem with litter or vandalism there. In order to restore Central Plaza to its former glory, then, we recommend that the city lift its prohibition on skateboarding in the plaza."- GRE - 2025
