Concept:Arranging sentence parts in a logical sequence based on the context and flow of ideas between a fixed opening and closing sentence.
Explanation:The opening sentence states Riya enjoys learning languages. The closing sentence says she wants to be a polyglot.
Sentence R ("She knows some German") introduces her existing knowledge. This should come first.
Sentence Q ("Her Spanish is improving") shows progress in another language. It follows logically after R.
Sentence S ("She uses an app to practice daily") describes her regular practice routine. It fits next to show how she improves.
Sentence P ("She attends French classes") tells about her active learning effort. It comes last, right before the final goal.
Thus the correct order is R → Q → S → P, which matches option A.
Answer:A. RQSP
