The correct answer is option (D):
QRSP
The correct answer is QRSP because it creates the most grammatically sound and logically coherent sentence. Let's break down why:
* **Q (Everything on or)** logically introduces the subject of the sentence - the things being affected by gravity.
* **R (Near the surface of)** provides context, specifying the location where the subject is being acted upon.
* **S (The earth is attracted)** introduces the action (attraction) and the source of that action (the earth).
* **P (By the mass of earth)** completes the sentence, clarifying the cause of the attraction (the earth's mass).
Putting it all together, the correctly sequenced sentence is: "Everything on or near the surface of the earth is attracted by the mass of earth." This makes grammatical sense and communicates a clear scientific concept (gravity).
The other options don't create logical or grammatically correct sentences. For example, SPRQ starts with "The earth is attracted..." which is a passive voice construction that is less clear than the active voice in the correct answer and disrupts the flow.
