Answer:

The analysis is: acetic acid will be too low because of the acid that may still be in the water.  

Explanation:

We know that the amount of acetic acid in vinegar is determined by the volumetric titration of acetic acid with standardized NaOH solution; because it doesn't affect the number balance of hydronium and hydroxide ions.

This percent by mass of acetic acid will be too low because of the acid that may still be in the water.  

Now if the deionized water is contaminated in this case with carbonic acid, so there would be a consumption of a higher amount of NaOH for neutralization as a result. Therefore, the amount will depend on many factors.

The correct answer is known as "foreclosed identity".

Foreclosed Identity refers to the identity of a person that has been discovered in his or her self, yet that person has not tried to explore or try other things, options or ideas. Just like in the situation wherein Matthew desires to be a doctor, though he has low grades in biology and low scores in the standardized tests, he continues to desire to become a doctor and does not consider other field of work.

The reason that Shirley's testimony was invalid because she's a minor and by that, that memories about the robbery that she remembers could harm her and would most likely be susceptible to the suggestion. That is why the court would make her testimony as invalid and wouldn't consider it in any way even though she is the witness of the robbery.
