Directions: Each item in the section has a sentence with parts labeled . Read each sentence to find out whether there is any error in any underlined part and indicate your response in the Answer Sheet against the corresponding letter . Turbidity current is a fast-moving current (A) that sweeps down submarine canyons, (B) carrying sand and mud into the deep sea. (C) No error (D)
Explanation
The sentence provided is grammatically and scientifically accurate. A turbidity current is defined as a fast-moving, sediment-laden gravity flow that moves down the continental slope and through submarine canyons [1][2]. These currents are characterized by their ability to transport vast quantities of sand, mud, and organic matter from the shelf edge into the deep-sea basins [1][3]. Scientific observations confirm they 'sweep down' these canyons, often reaching high velocities and acting as a primary mechanism for deep-ocean sedimentation. The singular subject 'Turbidity current' is correctly paired with the singular verb 'is', and the subsequent relative clauses 'that sweeps...' and 'carrying...' correctly modify the subject. Since all parts (A), (B), and (C) are factually and syntactically correct, the answer is 'No error'.
