The correct answer is: illusion.
An illusion is a false perception of reality. In this case, the speaker is saying that the complete eradication of poverty is not possible. This is because poverty is a complex issue with many causes, and it is difficult to address all of these causes. Additionally, poverty is often cyclical, meaning that people who are born into poverty are more likely to remain in poverty. As a result, it is difficult to break the cycle of poverty.
The other options are incorrect because they are all true statements. Truth is a statement that is in accordance with reality. Fact is a statement that is based on evidence. Reality is the state of things as they actually exist, rather than as they may appear or might be imagined. Actuality is the state of things as they exist at the present time.
In conclusion, the correct answer to the question “The complete eradication of poverty from our country is really an illusion” is illusion. This is because poverty is a complex issue with many causes, and it is difficult to address all of these causes. Additionally, poverty is often cyclical, meaning that people who are born into poverty are more likely to remain in poverty. As a result, it is difficult to break the cycle of poverty.
