about, above, across, after, against, along, amid, among, around, at, before, behind, below,

into, like, near, on, onto, out, outside, over, past, regarding, since, through, throughout, to, toward,

phrases
a participial phrase may be placed within a sentence.
ex - a bus driver, stopped at a traffic light, checked her mirror.
circle the participial phrase. draw an arrow to the word it modifies (goes over to).
the alumni group, cheering loudly, stood and waved.

Explanation:

Prepositional phrases start with prepositions (e.g., "during", "within") and usually don't form the subject or verb. Deleting them helps identify key sentence parts. Participial phrases are verb - related modifiers (e.g., "stopped at a traffic light", "cheering loudly"). For "Within hours, the detective had secured a search warrant for a house in York", the subject is "the detective" (underlined once) and the verb phrase is "had secured" (underlined twice), with "Within hours" and "for a house in York" being prepositional phrases. For "The alumni group, cheering loudly, stood and waved", the participial phrase "cheering loudly" modifies "the alumni group", so circle "cheering loudly" and draw an arrow from it to "The alumni group".

Answer:

For "Within hours, the detective had secured a search warrant for a house in York": Subject - the detective (underlined once), Verb/verb phrase - had secured (underlined twice). For "The alumni group, cheering loudly, stood and waved": Circle "cheering loudly", draw arrow to "The alumni group".
