The Choice C is the best answer. In lines 10-17, the passage illustrates how the cost of solar energy has dropped in recent years. researchers at the National Renewable Energy Laboratory have made flexible solar cells on a new type of glass from Corning called Willow Glass, which is thin and can be rolled up.” Overall, the passage can be regarded as an objective overview of the solar panel industry delivered by a journalist covering the field.
According to the statement
we have to find the correct statement with the help of the given passage.
So, For this purpose, we know that the
In the given passage, the point of view according to the given options is discussed below.
The Choices A and D are incorrect because the author does not present himself as either a consumer who plans to buy solar panels or a hobbyist with a personal interest in solar panel technology. Rather, the author focuses on developments in solar technology. Choice B is incorrect because the passage does not discuss research methods used in the solar panel field but rather the technologies that exist in the field.
So, The Choice C is the best answer. In lines 10-17, the passage illustrates how the cost of solar energy has dropped in recent years. researchers at the National Renewable Energy Laboratory have made flexible solar cells on a new type of glass from Corning called Willow Glass, which is thin and can be rolled up.” Overall, the passage can be regarded as an objective overview of the solar panel industry delivered by a journalist covering the field.

Your answer is correct in the sense that 14 ≤ x ≤22 since the temperature is 18 ° plus/minus 4°. However, the wording of the problem implies that it wants your final answer in terms of absolute value.
Based on your work, you understand the basics of the problem, and you correctly expressed it as an inequality. The problem is how to express it with an absolute value and only one inequality sign.
The word "within" implies that ≤ is the correct symbol, rather than < (you were correct to use that symbol)
We can word the expression in this way: The difference between the real temperature and 18° is less than or equal to 4. Difference in this sense is a positive number whether the real temperature is lower or higher than 18, so absolute value is implied.
We can express it mathematically this way:
|18-x| ≤ 4
Plug a few numbers in for X to make sure it makes sense.
If X equals 16 (within the range), |18-16| = 2, which is less than 4
If X equals 20, |-2| equals 2, which is less than 4
If X equals 10, |18-10| = 8, does not comply with our inequality.
