B
Correct answer
Explanation
The series follows the pattern of n^3 + 1. For n=1, 1^3+1=2; for n=2, 2^3+1=9; for n=3, 3^3+1=28; for n=4, 4^3+1=65. The next term for n=5 is 5^3+1, which equals 125+1 = 126.

The sum of interior angles in any triangle is always 180 degrees. This is a fundamental theorem in geometry - angle sum is constant regardless of triangle type (equilateral, isosceles, or scalene).
B
Correct answer
Explanation
To get 125 = 5^3 cubes, make 4 cuts along each dimension. Total cuts = 4+4+4 = 12. Each set of parallel cuts creates one more piece than cuts: 4 cuts → 5 pieces. 5 × 5 × 5 = 125 cubes.

C
Correct answer
Explanation
The verb 'enter' can be used transitively without a preposition when followed immediately by a location. 'He entered room' follows this pattern, though 'the room' would be more natural with a definite article. Prepositions like 'in' or 'into' are redundant after 'enter'.
B
Correct answer
Explanation
In the construction 'X is called Y', when Y is a noun phrase, no preposition is used. 'Telugu is called the Italian of the East' correctly uses zero preposition. 'As' would create 'Telugu is called as the Italian', which is incorrect grammar.
D
Correct answer
Explanation
Scissors is a plural noun (even though it refers to one object), so it takes a plural verb. 'My scissors are on the table' is correct. Using 'is' (singular) is a common error - scissors, pants, glasses, and similar words always take plural verbs.
C
Correct answer
Explanation
The structure 'I don't think' followed by an independent clause doesn't require a conjunction or comma. 'I don't think he will come for party' (though 'for the party' would be better) stands correctly without so/that. Adding 'that' creates a noun clause which works but isn't required.
B
Correct answer
Explanation
Shoes are counted in pairs. 'A pair of shoes' is the correct expression. 'Couple' typically refers to two people in a relationship, 'set' is for groups of related items, and 'none' is incorrect.
C
Correct answer
Explanation
Similar to question 127731, 'I don't think' can be followed directly by an independent clause. 'I don't think its necessary' works without a conjunction. 'That' would create 'I don't think that its necessary', which is grammatically valid but not required.
