Reading Passage & Questions

Passage: GLOBAL WARMING IN NEW ZEALAND

Paragraph 1 For many environmentalists, the world seems to be getting warmer. As the country closest to the South Polar Region, New Zealand has seen an upward trend in its average temperature over the past few years. However, temperatures in New Zealand are projected to rise by 4°C over the next century, while the polar region will see an increase of more than 6°C. This difference in temperature patterns stems from the surrounding ocean, which acts like an air conditioner. Thus, New Zealand is comparatively fortunate.

Paragraph 2 Scientifically speaking, this temperature phenomenon in New Zealand originates from what researchers call the “SAM” (Southern Annular Mode), which refers to the wind belt circling the Southern Oceans, including New Zealand and Antarctica. Yet, recent work has revealed that changes in the SAM have resulted in a weakening of moisture during the summer and increased rainfall in other seasons. A greater problem may prove to be more severe droughts for agricultural activities due to increased soil water loss, leading to poorer harvests before winter, when rainfall arrives too late to help.

Paragraph 3 Among all the calamities posed by drought, moisture deficit ranks first. Moisture deficit is the gap between the water plants need during the growing season and the water the earth can provide. Measures of moisture deficit in New Zealand have been at their highest since the 1970s. Meanwhile, ecological analyses clearly show that moisture deficit affects crops at different growth stages. If a moisture deficit occurs during a crucial growth stage, it will cause about a 22% reduction in grain yield compared to a deficit during the vegetative phase.

Paragraph 4 Global warming is not only affecting agricultural production. When scientists say the country’s snowpack and glaciers are melting at an alarming rate due to global warming, the climate is placing another strain on local areas. For example, as global warming progresses and the snow line falls, the local skiing industry faces a crisis. The snow line may move upward as temperatures rise, causing snow at lower elevations to melt earlier. Fortunately, the local skiing industry may be able to weather these tough periods, as snowfall quantities in some areas are likely to increase.

Paragraph 5 What is the reaction in glacier regions? Climate change is reflected in the glacier regions of southern New Zealand and other land covered by ice and snow. A glacier’s reaction to climatic change involves a complex chain of processes. Over periods ranging from years to several decades, cumulative changes in mass balance cause changes in volume and thickness, which affect ice flow through altered internal deformation and basal sliding. This dynamic reaction eventually leads to changes in glacier length, causing glacier tongues to advance or retreat. Undoubtedly, glacier mass balance is a more direct signal of annual atmospheric conditions.

Paragraph 6 The latest research from the National Institute of Water and Atmospheric Research (NIWA) shows that glacier lines keep moving upward due to the impacts of global warming. Further ice losses are evident in the Mt. Cook Region. By 1996, a 14 km long sector of the glacier had melted, forming a melt lake (Hooker Lake) of significant volume. Melting of the glacier front at a rate of 40 m/yr will cause the glacier to retreat at a relatively uniform rate. Therefore, the lake will continue to grow until it reaches the glacier bed.

Paragraph 7 A direct result of melting glaciers is the change in high tides, which serves as a primary factor in sea-level rise. The trend of rising sea levels threatens the groundwater system due to hyper-saline groundwater, which could potentially decrease agricultural production. Many experts believe the best way to counter this trend is to take a longer-term view of sea-level change in New Zealand. Indeed, coastal boundaries need to be upgraded and redefined.

Paragraph 8 There is no doubt that global warming has affected New Zealand in many aspects. Addressing global warming requires the joint efforts of local people and experts to overcome these tough times. For instance, farmers are taking a long-term, multi-generational approach to adjust breeds and species according to temperature changes. Agriculturists are also finding ways to tackle the problems posed to the soil. In broad terms, moving forward, the systemic resilience that has existed in the ecosystem for a long time will continue.

Paragraph 9 What about the reaction of animals? Experts have been surprised to discover that animals have unconventional adaptations to global warming. A study of sea turtles on a few northern beaches in New Zealand found it fascinating that sea turtles can become male or female depending on the temperature. Further research will attempt to determine how rising temperatures affect the ratio of sex reversal during their growth. Clearly, the temperature of the nest plays a vital role in the sex of baby turtles.

Paragraph 10 Tackling the problems of global warming is never easy in New Zealand, as records show that the slow process of global warming may have different impacts on various regions. For New Zealand, carbon dioxide emissions account for only 0.5% of the world’s total, which meets governmental standards. However, New Zealand’s efforts are only the tip of the iceberg. So far, global warming remains a global issue with an ambiguous future.

However, recent research has revealed that changes in the SAM in New Zealand have led to a weakening of moisture during the summer and more rainfall in other seasons. A bigger problem may be more severe droughts for agricultural activities due to increased water loss from the soil, leading to poor harvests before winter, when rainfall arrives too late to save the crops.

Among all the calamities caused by drought, moisture deficit ranks first. Moisture deficit is the gap between the water plants need during the growing season and the water the earth can provide. Measures of moisture deficit have been at their highest since the 1970s in New Zealand. Meanwhile, ecological analyses clearly show that moisture deficit affects different growth stages of crops. If a moisture deficit occurs during a crucial growth stage, it will cause about a 22% reduction in grain yield compared to a deficit during the vegetative phase.

Global warming is not only affecting agricultural production. When scientists say the country’s snowpack and glaciers are melting at an alarming rate due to global warming, the climate is placing another burden on local areas. For example, when global warming is accompanied by a falling snow line, the local skiing industry falls into crisis. The snow line may move upward as temperatures rise, and then the snow at the bottom will melt earlier. Fortunately, the local skiing industry will have a favorable opportunity to weather this difficult period because snowfall in some areas is likely to increase.

What is the reaction of the glacier region? Climate change can be reflected in the glacier regions of southern New Zealand or land covered by ice and snow. A glacier’s reaction to climatic change involves a complex chain of processes.

There is no doubt that global warming has affected New Zealand in many aspects. The focus on global warming should be based on the joint efforts of local people and experts to overcome this tough period. For instance, farmers are taking a long-term, multi-generational approach to adjust breeds and species according to temperature. Agriculturists are also finding ways to tackle the problems posed to the soil. In broad terms, moving forward, the systemic resilience that has existed for a long time in the ecosystem will continue.

Answer Key and Detailed Explanations

27. D

Question: What is the main idea of the first paragraph?

Explanation: Paragraph 1 clearly states that temperatures in New Zealand will only rise by 4°C, less than in the polar region (more than 6°C). The reason (“stem from”) is that the surrounding ocean acts like an air conditioner. Option D summarizes this accurately: the temperature increase is lower because it is surrounded by the sea.

28. B

Question: What is one effect of the wind belt that circles the Southern Oceans?

Explanation: Paragraph 2 explains that this wind belt (SAM) weakens moisture in the summer, leading to a bigger problem: “heavier droughts for agricultural activities because of more water loss from soil.” This corresponds to option B (facing more frequent droughts in hotter months/summer).

29. C

Question: What does “moisture deficit” mean for grain and crops?

Explanation: Paragraph 3 provides a clear definition: “Moisture deficit is the gap between the water plants need during the growing season and the water the earth can offer.” Option C matches this definition perfectly.

30. C

Question: What changes will happen to the skiing industry due to global warming?

Explanation: At the end of paragraph 4, it states: “Fortunately, it is going to be favorable for the local skiing industry to tide over tough periods since the quantities of snowfall in some areas are more likely to increase.” Choose C.

31. A

Question: Cumulative changes over a long period of time in mass balance will lead to…

Explanation: Paragraph 5 states: “cumulative changes in mass balance cause volume and thickness changes.” This matches option A.

32. A

Question: Why does the writer mention NIWA in the sixth paragraph?

Explanation: At the beginning of paragraph 6, the author mentions NIWA’s research to show that glacier lines are moving. Immediately after, the author uses the specific example of the Mt. Cook Region and Hooker Lake to illustrate the impact of this melting. Choose A (To use a specific example to explain the effects of glacier melting).

33. melting glaciers

Summary Question: The major reason for the increase in sea level is connected with…

Explanation: The beginning of paragraph 7 states: “A direct result of the melting glaciers is the change of high tides that serves as the main factor for sea level rise.”

34. agricultural production

Summary Question: The increase in sea level is also said to pose a threat to the underground water system, the destruction of which will lead to a high probability of reduction in…

Explanation: Paragraph 7 continues: “…bring a threat to the groundwater system… and then pose a possibility to decrease the agricultural production.”

35. coastal boundaries

Summary Question: In the long run, New Zealand may have to improve the… if they want to diminish the effect of changes in sea levels.

Explanation: At the end of paragraph 7, the author concludes: “Indeed, the coastal boundaries need to be upgraded and redefined.” “Upgraded” is equivalent to “improve.”

36. NOT GIVEN

Statement: Farmers are less responsive to climate change than agriculturists.

Explanation: Paragraph 8 mentions both “farmers” (adjusting breeds) and “agriculturists” (finding ways to tackle soil problems). However, the passage does NOT compare who is more or less responsive.

37. NO

Statement: The agricultural sector refuses to take action to deal with climate change.

Explanation: This contradicts paragraph 8, where the author states that both farmers and agricultural experts are actively seeking solutions (“taking a long term… approach,” “find ways to tackle the problems”).

38. NO

Statement: Turtles are often unaffected by climate change.

Explanation: Paragraph 9 clearly states: “…sea turtles can become male or female according to the temperature.” They are clearly deeply affected by global warming.

39. YES

Statement: Global warming is occurring slowly, and it may have different effects on different areas in New Zealand.

Explanation: The beginning of paragraph 10 confirms this exactly: “…records show the slow process of global warming may have a different impact on various regions.”

40. NO

Statement: New Zealand must cut carbon dioxide emissions if they want to solve the problem of global warming.

Explanation: Paragraph 10 points out that NZ’s emissions account for only 0.5% of the global total and “has met the governmental standard.” Furthermore, their efforts are only “a tip of the iceberg” because this is a “world issue.” This means NZ cutting emissions alone cannot solve the entire problem, making the statement logically inconsistent with the author’s view.
