Which choice synthesizes the notes clearly and accurately?
- Dr. Meera Patel claimed that testing wastewater is a quicker method for viruses, and it has become a popular epidemiological tool.
- Epidemiologist Dr. Meera Patel explained that monitoring viruses in wastewater can reveal community infection patterns several days earlier than traditional clinical testing does. (correct answer)
- At a conference, wastewater surveillance was discussed by Dr. Meera Patel, who studies epidemics and recommends it before clinical tests.
- The conference featured Dr. Meera Patel, whose wastewater work tracks outbreaks, something faster than clinical data in most circumstances.
Explanation: When you encounter synthesis questions on the PSAT, you're being asked to combine information from multiple bullet points into one coherent, accurate statement. The key is capturing all the essential details without adding, omitting, or distorting any information. Choice B correctly synthesizes all three bullet points: it identifies Dr. Patel as an epidemiologist, specifies that wastewater monitoring tracks viruses to reveal community infection patterns, and includes the crucial timing claim that this method works "several days earlier than traditional clinical testing." This choice preserves the precise meaning and scope of the original notes. Choice A is too vague and adds unsupported information. It mentions wastewater testing being "popular" as an epidemiological tool, which isn't stated in the notes, and fails to specify the timing advantage or what exactly is being detected. Choice C misrepresents the claim by suggesting Dr. Patel "recommends" wastewater surveillance "before clinical tests," implying it should replace rather than complement clinical testing. The notes only claim it detects trends earlier, not that it should be used instead. Choice D is unnecessarily awkward and imprecise. The phrase "something faster than clinical data in most circumstances" dilutes the specific claim about detecting trends "days before" and adds the qualifier "most circumstances," which isn't in the original notes. For synthesis questions, read each bullet point carefully, then find the choice that includes every key detail without adding extra claims or changing the meaning. Accuracy and completeness are both essential.
