Correct Answer: D

Rationale: The correct answer is 'Our.' In this sentence, the possessive pronoun 'Our' is needed to show ownership and make the sentence grammatically correct. 'Screaming our took the shopkeeper by surprise' indicates that the shopkeeper was surprised by the screaming of a group or individuals related to 'our.' Choices A, B, and C are incorrect as they are pronouns referring to people ('We', 'They', 'Them'), not possessive pronouns that indicate ownership.

Correct Answer: A

Rationale: The correct answer is 'amount.' In this context, 'amount' is used to describe the intensity or level of pain, which is an uncountable noun. 'Frequency' (B) refers to how often something occurs, 'number' (C) is used for countable objects, and 'amplitude' (D) is typically used in the context of sound or waves, not pain.

Correct Answer: C

Rationale: In the sentence 'The bird flew across the blue sky,' 'bird' is the noun. A noun is a word that represents a person, place, thing, or idea. In this sentence, 'bird' represents a living creature, making it the noun. 'Across' is a preposition used to show the relationship between 'flew' and 'sky.' 'Flew' is a verb indicating an action, and 'blue' is an adjective describing the sky.

Correct Answer: D

Rationale: The word 'laying' is used incorrectly in the sentence. The correct word should be 'laying' when referring to the action of setting up a brick foundation. Therefore, the correct choice is 'D: laying.' In this context, 'lying' would imply being in a horizontal position, which is not the intended meaning. Choices A, B, and C are not incorrect in the sentence and do not affect the clarity or correctness of the statement.

Correct Answer: B

Rationale: The correct preposition to use in this context is 'with.' 'Felix was pleased with the progress he had made in his program' indicates that Felix's satisfaction is directly related to the progress he achieved. 'Among' is incorrect as it implies being part of a group, 'regards' is not a suitable preposition in this context, and 'besides' does not convey the intended meaning of satisfaction with the progress.
