Explanation:

Paula's Electric Bills Increase
- After replacing her old air conditioner with a new, energy-efficient unit, Paula noticed an increase in her electric bills.

Analysis of Each Option:

a) Paula installed an electricity-intensive indoor tanning bed after she replaced her air conditioning unit:
- This could explain the increase in electric bills as the new tanning bed consumes a significant amount of electricity.

b) The new air conditioner uses a smaller share of the electricity used by Paula’s home than did the old unit:
- This option does not contribute to explaining the increase in electric bills as it implies that the new air conditioner is more energy-efficient, which should result in lower electricity consumption.

c) Following the installation of her new air conditioner, Paula’s neighborhood experienced a prolonged and severe heat wave, requiring heavy use of the new unit:
- This could be a contributing factor as increased usage of the air conditioner during a heatwave would lead to higher electricity consumption.

d) Paula’s electricity costs increased by 15 cents per kilowatt-hour after she replaced her air conditioner:
- This information suggests a direct correlation between the increase in electric bills and the replacement of the air conditioner.

e) Soon after the new air conditioner was installed, Paula adopted a child, doubling the size of her household:
- This could also explain the increase in electric bills as a larger household would consume more electricity for various activities.

In Conclusion:
- Option B does not contribute to explaining the increase in electric bills, as a more energy-efficient air conditioner should result in lower electricity consumption. The other options provide plausible explanations for Paula's increased electric bills.

The correct answer here is the one that does not explain the apparent paradox. That the new unit uses a smaller share of total electricity is consistent with its being more energy efficient. It does not explain how her electric bills could have gone up despite her installation of the more efficient unit; all other answers provide possible resolutions of such apparent paradox.

Similar GMAT Doubts

Over the past 50 years, expansive, low-density communities have proliferated at the edges of many cities in the United States and Canada, creating a phenomenon known as suburban sprawl. Andres (5) Duany, Elizabeth Plater-Zyberk, and Jeff Speck, a group of prominent town planners belonging to a movement called New Urbanism, contend that suburban sprawl contributes to the decline of civic life and civility. For reasons involving the flow of (10) automobile traffic, they note, zoning laws usually dictate that suburban homes, stores, businesses, and schools be built in separate areas, and this separation robs people of communal space where they can interact and get to know one another. It is as difficult (15) to imagine the concept of community without a town square or local pub, these town planners contend, as it is to imagine the concept of family independent of the home.Suburban housing subdivisions, Duany and his (20) colleagues add, usually contain homes identical not only in appearance but also in price, resulting in a de facto economic segregation of residential neighborhoods. Children growing up in these neighborhoods, whatever their economic (25) circumstances, are certain to be ill prepared for life in a diverse society. Moreover, because the widely separated suburban homes and businesses are connected only by “collector roads,” residents are forced to drive, often in heavy traffic, in order to (30) perform many daily tasks. Time that would in a town center involve social interaction within a physical public realm is now spent inside the automobile, where people cease to be community members and instead become motorists, competing for road space, (35) often acting antisocially. Pedestrians rarely act in this manner toward each other. Duany and his colleagues advocate development based on early-twentieth- century urban neighborhoods that mix housing of different prices and offer residents a “gratifying (40) public realm” that includes narrow, tree-lined streets, parks, corner grocery stores, cafes, small neighborhood schools, all within walking distance. This, they believe, would give people of diverse backgrounds and lifestyles an opportunity to interact (45) and thus develop mutual respect.Opponents of New Urbanism claim that migration to sprawling suburbs is an expression of people’s legitimate desire to secure the enjoyment and personal mobility provided by the automobile and the (50) lifestyle that it makes possible. However, the New Urbanists do not question people’s right to their own values; instead, they suggest that we should take a more critical view of these values and of the sprawl conducive zoning and subdivision policies that reflect (55) them. New Urbanists are fundamentally concerned with the long-term social costs of the now-prevailing attitude that individual mobility, consumption, and wealth should be valued absolutely, regardless of their impact on community life.Which one of the following, if true, would most weaken the position that the passage attributes to critics of the New Urbanists?

Inspired by earlier artists but developed as a genre in its own right in the last few decades of the twentieth century, installation art is now recognized by academic institutions. It has long been seen as an example of anti-establishment artwork, since it is typically created in public spaces and involves the use of everyday materials, unlike conventional artwork that, even though usually meant for public consumption, is created in a private space. Installation art in contemporary times also uses emerging forms of artistic representation such as videos, social networks and aspects of virtual reality. This form of art, like traditional art, can be either realistic or abstract in its representation of reality.Straddling the boundaries between sculpture and painting, installation art gives more priority to the intention of the artist rather than the physical form or structure of the art: its purpose is often to relay a specific message through the medium chosen by the artist. Artists such as Banksy, known only by his pseudonym and famous for his street art that is meant as a caricature of political institutions, often use their art as a medium of socio-political activism.From the audiences perspective, installation art also gives an unprecedented amount of importance to the viewers subjective perception of the artwork. The intention of the artist is therefore supplemented by the way in which viewers perceive the artwork. This vision of art overturns the traditional Platonic view of image theory, which gives the form and intention of the artwork far more predominance than external perspectives on the work. There are no ideal forms in the creation and exhibition of installation art. This attribute is as it should be: art, after all, requires both an artist and an audience in order to flourish, and nowhere is this creator-viewer relationship more prominent than in the study and appreciation of installation art, which embraces the flawed and fragmented nature of reality.Which of the following CANNOT be inferred from the passage?
