For each question, select the best answer of the choices given and explain why the chosen answer is the right fit. You have to consider the statements to be true even if they seem to be at variance from the commonly known facts.

Topsoil which is high in organic matter, fertility and soil life majorly contributes on the growing of crops. Soil erosion reduces cropland productivity and causes the pollution of watercourses, wetlands and lakes.
Which among the following option does not show the step taken to prevent this?
A) Using of contour ploughing will help reduce soil erosion.
B) Soil erosion is a result of mankind’s unwise actions such as overgrazing or unsuitable cultivating practices.

D) Use of proper drainage canals.
E) Terracing of the sloping fields.
3) Statements: Tomato is considered a vegetable by cooks or chefs because it is used in savory items rather than sweets.

Answers :
Directions (1-3):
1) Answer: A
The workers quit their jobs and put up a strike against the employer because the employer behaved inappropriately with one of the workers. Therefore, options c and e are incorrect. The strike forced the employer to publicly apologize for his behaviour. Hence, option a is correct. Option b is out of context. The statement does not say anything about the employer’s thoughts, so option d is eliminated.
2) Answer: B
Option b would be the correct solution as only that option does not talk about ways on how to prevent soil erosion. It talks about one of the reasons which causes it. There are natural ways as well as some human activities that will result in soil erosion. Human activities include over grazing the fields and such.
Other options talks about methods by which soil erosion can be reduced or prevented.
3) Answer: A
Tomato is considered a vegetable by chefs and cooks, therefore option b is eliminated. Tomato is technically a fruit, and also a part of berry family, therefore option c is incorrect. Tomato is considered a vegetable because it is commonly used for savory items instead of sweets but the statement does not say it cannot be used for sweets so option d is incorrect. Option e cannot be asserted because the statements say that berries usually have seed and it says nothing about why tomato is a fruit. Hence statement “Tomato is technically a fruit but considered as a vegetable by cooks and chefs” is correct.
Directions (1-5):
4) Answer: A
According to the given information,
Statements: X α U, V δ X, X β Y, Z δ X, W α Z
On converting: X > U, V < X, X ≥ Y, Z < X, W > Z
On combining: Y ≤ X; X > Z < W; U < X > V
Conclusions:
I). U γ Y → U = Y → False (as U < X, Y ≤ X; U = Y is not possible)
II). V γ Z → V = Z → False (as X > V, X > Z, clear relation between V and Z cannot be determined)
III). W α X → W > X → False (as X > Z < W; clear relation between W and X cannot be determined)
Hence none is true.
5) Answer: E
Statements: D α B, E β D, G α C, A ε G, B γ G
On converting: D > B, E ≥ D, G > C, A ≤ G, B = G
On combining: A ≤ G = B < D ≤ E; G > C
Conclusions:
I). A δ D → A < D → True
II). A α D → A > D → False (as A ≤ G = B < D, so A<d)
III). C γ A → C = A → False (as A ≤ G; G > C, clear relation between A and C cannot be determined)
Hence, only conclusion I is true. Therefore, “none of the above” is true.
