Pinpoint 890 Answer & Full Analysis
The first clue, "A+", opens the puzzle with a deliberately wide field. In LinkedIn Pinpoint, that first reveal is rarely enough by itself, so the smart move is to test a few possible links without overcommitting.
The second clue, "B-", is where the answer search starts to tighten. A strong answer must connect both "A+" and "B-" in a repeatable way, not just through a vague theme.
The third clue, "AB+", creates the pivot. By now, "Blood types" should begin to explain the clue set as a shared word, category, or phrase pattern instead of a lucky overlap.
The fourth clue, "O+ (the most common)", and the final clue, "O- (universal red cell donor)", finish the check. If the same answer still works after those extra reveals, the solution is much stronger than an early one-clue guess.
Read together, A+, B-, AB+, O+ (the most common), and O- (universal red cell donor) all point back to "Blood types". That is why "Blood types" is the best fit for LinkedIn Pinpoint #890.
Why this answer fits
"Blood types" fits because it can explain A+, B-, AB+, O+ (the most common), and O- (universal red cell donor) under one answer. The clue set is not asking for five separate facts; it is asking for the common connection that survives each reveal in the LinkedIn Pinpoint sequence.
