Understanding the Passage and the Question
The question asks us to choose the most appropriate word to fill in blank number 7 in the provided passage. The passage discusses the topic of global warming, its causes (human actions like burning fossil fuels, deforestation), and its consequences, specifically mentioning the impact on agriculture.
We need to read the sentence containing blank 7 carefully and consider the meaning and context to select the best fitting word from the given options.
Analyzing Blank Number 7
The sentence with blank 7 is:
"Global warming has led to changes in temperature and rainfall patterns which have severely (7) ______ agriculture."
This sentence describes how the changes caused by global warming impact agriculture. We need a word that means 'had a significant effect on' or 'damaged' in this context.
Evaluating the Options for Blank 7
Let's examine each option provided for blank number 7:
- renewed: This word means to make something new again or resume something. In the context of global warming's impact, 'renewed agriculture' would imply a positive or restorative effect, which contradicts the general understanding of how global warming affects farming (usually negatively). So, this option is not suitable.
- reduced: This word means to make something smaller in size, amount, or degree. While global warming often leads to reduced agricultural yields, the blank asks what global warming has done to agriculture itself as a system or activity. 'Reduced agriculture' isn't the most natural phrasing to describe the overall impact; it's more a consequence of being affected.
- affected: This word means to have an effect on; make a difference to. Global warming's changes in weather patterns definitely have an effect on agriculture, usually a detrimental one. "Severely affected agriculture" means agriculture has been strongly impacted or influenced by global warming. This fits the context well.
- effected: This word means to cause something to happen; bring about. While global warming effects changes, 'effected agriculture' usually implies bringing agriculture into existence or accomplishing it. This is not the intended meaning here. The correct word for having an impact or influence is 'affected'.
Determining the Most Appropriate Word
Based on the analysis of the options and the context of the sentence, the word "affected" is the most appropriate choice. It accurately describes the influence or impact that changes in temperature and rainfall patterns have had on agriculture due to global warming.
Therefore, the complete sentence would be: "Global warming has led to changes in temperature and rainfall patterns which have severely affected agriculture."
Revision Table: Understanding Affect vs Effect
| Word | Part of Speech (Common Use) | Meaning | Example in Context |
|---|---|---|---|
| Affect | Verb | To influence; to have an impact on | The weather change will affect the crops. |
| Effect | Noun | A result or consequence of an action | One effect of pollution is poor air quality. |
| Effect | Verb (less common) | To cause something to happen; to bring about | They sought to effect a change in policy. |
In the given sentence, we need a verb to describe what the changes have done to agriculture. "Affected" is the correct verb meaning 'influenced' or 'had an impact on'.
Additional Information on Global Warming Impacts
Global warming is a significant environmental challenge with wide-ranging impacts beyond agriculture. Some key areas affected include:
- Sea Levels: Rising global temperatures cause glaciers and ice sheets to melt, leading to an increase in sea levels, which threatens coastal communities.
- Extreme Weather: More frequent and intense heatwaves, droughts, floods, storms, and wildfires are linked to climate change.
- Ecosystems: Changes in temperature and climate patterns can disrupt ecosystems, leading to species migration or extinction.
- Water Resources: Altered rainfall patterns and melting glaciers affect the availability of fresh water in many regions.
- Human Health: Heat stress, respiratory problems from poor air quality, and the spread of vector-borne diseases can increase due to global warming.
Addressing global warming requires global cooperation and significant changes in energy consumption and conservation practices.
