Modernism (in literature) focused on all of the following aspects except: question 2 options: a) appreciation of nature b) alienation of the individual c) corruption of old-fashioned values d) brutality of war.
The only option that modernism didn't focus on is; A: Appreciation of Nature
What is Modernism?Literary modernism originated in the late 19th and early 20th centuries primarily in Europe and North America. Modernism is characterized by a self-conscious break with traditional ways of writing, in both poetry and prose fiction writing.
The modernist movement was not in line with the previous Romantic period due to the fact that one focused on nature and existence while the modernist authors were more focused on the inner self and consciousness.
Thus, the correct answer is option A.

Consider the reaction n2 + 3 h2 → 2 nh3. How much nh3 can be produced from the reaction of 74. 2 g of n2 and 14. 0 moles of h2?
Convert 74.2 g N₂ to moles. (N₂ molar mass ≈ 28.014 g/mol)
(74.2 g) (1/28.014 mol/g) ≈ 2.65 mol N₂
According to the balanced reaction, 1 mol N₂ and 3 mol H₂ get consumed together to produce 2 mol NH₃, which means we consume up to
3 (2.65 mol N₂) ≈ 7.95 mol H₂
That is, all the N₂ is consumed and we have an excess of about 6.05 mol H₂. We end up with
2 (2.65 mol N₂) ≈ 5.30 mol NH₃
or (with NH₃ molar mass ≈ 17.031 g/mol)
(5.30 mol) (17.031 g/mol) ≈ 90.3 g NH₃

A sorted list of numbers contains 128 elements. Which of the following is closest to the maximum number of list elements that can be examined when performing a binary search for a value in the list?
The maximum number of list elements that can be examined when performing a binary search for a value in the list is eight (8).
What is a binary search?Binary search can be defined as an efficient algorithm that is designed and developed for searching an element (information) from a sorted list of data, especially by using the run-time complexity of Ο(log n)
Note: n is the total number of elements in a list.
In this scenario, the binary search algorithm would start at the middle of the sorted list and then it would eliminate half the elements repeatedly, until the desired value is found, which is at a maximum number of eight (8) examinations.

The radius of circle c is 6 units and the measure of central angle acb is radians. What is the approximate area of the entire circle? square units what is the approximate area of the entire sector created by central angle acb? square units what is the approximate area of the shaded region only? square units.
Answer:
113
28
22
Explanation:
Area of shaded region ≈ 95.2 square units, Area of entire circle ≈ 113.1 square units.
What is circumference?The circumference is the perimeter of a circle or ellipse in geometry. That is, the circumference would be the circle's arc length if it were opened up and straightened out to a line segment.
The first step is to find the measure of the central angle acb in radians:
Since the radius of circle c is 6 units, the diameter of the circle is 2*6 = 12 units. Therefore, the circumference of the circle is:
C = πd = π(12) = 12π units
The central angle acb cuts off a portion of the circumference that is proportional to its measure, so we can set up the following proportion to find the measure of the central angle in radians:
(angle measure)/(360°) = (arc length)/(circumference)
Where the arc length is the length of the portion of the circumference cut off by the central angle.
Substituting the given values, we get:
(angle measure)/360° = x/(12π)
Simplifying, we get:
(angle measure) = 360°(x/(12π)) = 30x/π
Now we can use this value to calculate the area of the entire circle and the area of the sector created by central angle acb:
Area of entire circle = [tex]\pi r^2[/tex] = π[tex](6)^2[/tex] ≈ 113.1 square units
Area of sector acb = (1/2)[tex](6^2)[/tex](angle measure) = (1/2)(36)(30x/π) = 540x/π square units
To find the area of the shaded region, we need to subtract the area of triangle abc from the area of sector acb.
The central angle acb is divided into two congruent angles of measure x/2, so the angle measure of triangle abc is (180° - x)/2. We can use the Law of Cosines to find the length of side ab:
[tex]ab^2[/tex] = [tex]ac^2 + bc^2[/tex] - 2acbc cos((180° - x)/2)
Substituting the given values, we get:
[tex]ab^2[/tex] =[tex]6^2 + 6^2[/tex] - 2(6)(6) cos((180° - x)/2)
Simplifying, we get:
[tex]ab^2[/tex] = 72 - 72 cos((180° - x)/2)
Taking the square root of both sides, we get:
ab = √(72 - 72 cos((180° - x)/2))
Now we can calculate the area of triangle abc:
Area of triangle abc = (1/2)ab(bc)sin((180° - x)/2)
Substituting the given values, we get:
Area of triangle abc = (1/2)(√(72 - 72 cos((180° - x)/2)))(6)(sin((180° - x)/2))
Finally, we can subtract the area of triangle abc from the area of sector acb:
Area of shaded region = Area of sector acb - Area of triangle abc
Area of shaded region = (540x/π) - (1/2)(√(72 - 72 cos((180° - x)/2)))(6)(sin((180° - x)/2))
Approximating with x = 1.5 radians (which is approximately 86°), we get:
Area of entire circle ≈ 113.1 square units
Area of sector acb ≈ 283.5 square units
Thus, the Area of shaded region ≈ 95.2 square units.
