Filling Blank 2 in the Aerobics Passage
Let's carefully examine the second blank in the passage about aerobics. The sentence is: "Aerobics is a system of exercise (1) ______ stimulates the heart and lungs to (2) ______ beneficial changes in the body." We need to find the most suitable word for blank (2) that describes what the stimulated heart and lungs do to beneficial changes in the body.
Analyzing the Options for Blank 2
Here are the provided options and an analysis of how each one fits the context:
- discover: To discover means to find something that already exists. The heart and lungs don't 'discover' beneficial changes; they are the agents that cause these changes to happen. So, 'discover' is not appropriate here.
- produce: To produce means to create or bring something into existence. Stimulating the heart and lungs through aerobics leads to the creation or generation of beneficial changes in the body (like stronger muscles, better oxygen flow, etc.). This word fits the context well.
- design: To design means to plan or create a drawing or pattern for something. The heart and lungs, in the context of exercise, don't 'design' changes; they facilitate them through physiological processes. 'Design' implies conscious planning, which isn't suitable here.
- assemble: To assemble means to put parts together. Beneficial changes in the body are not typically 'assembled' in this context. This word is used for putting together physical components.
Selecting the Most Appropriate Word
Based on the analysis, the word that best describes the action of the stimulated heart and lungs on beneficial changes is 'produce'. Aerobics stimulates these organs, which in turn leads to or produces positive outcomes in the body.
Therefore, the most appropriate word to fill in blank no. 2 is 'produce'.
Revision Table: Understanding Verb Meanings
| Word | Meaning | Applicability to Blank 2 |
|---|---|---|
| Discover | Find something previously unknown | Does not fit; changes are caused, not found. |
| Produce | Create or bring into existence | Fits well; heart/lungs cause beneficial changes. |
| Design | Plan or create a drawing/pattern | Does not fit; implies conscious planning, not physiological effect. |
| Assemble | Put parts together | Does not fit; changes are not 'assembled'. |
Additional Information: Aerobics and Body Changes
Aerobic exercise, also known as cardio, significantly impacts the cardiovascular and respiratory systems. Regular aerobic activity:
- Strengthens the heart muscle, allowing it to pump blood more efficiently.
- Improves lung capacity and efficiency, enhancing oxygen intake and carbon dioxide removal.
- Increases the number of red blood cells, which carry oxygen.
- Improves circulation, ensuring better delivery of oxygen and nutrients to muscles and organs.
- Helps manage weight by burning calories.
- Reduces the risk of chronic diseases like heart disease, stroke, type 2 diabetes, and some cancers.
- Boosts mood and reduces stress.
These are all examples of the "beneficial changes in the body" that aerobics helps to produce.
