One of the main functions of saliva is to buffer against acid from food and plaque, which contributes significantly to the formation of cavities. While there are several buffers in saliva, carbonic acid (H2CO3) has the highest concentration and has the greatest effect on pH.
(a) While the salivary concentration of carbonic acid stays at a fairly constant 1.3 mM, the level of bicarbonate (HCO3-) can vary with the rate that saliva flows from salivary glands. For low flow rates, the bicarbonate concentration is around 2 mM; for medium flow rates, it is 30 mM; and for high flow rates, around 60 mM. The pKa of carbonic acid at body temperature is 6.1. Assuming that the pH of Saliva is determined primarily by carbonic acid and bicarbonate, determine the pH of saliva for each of the three flow rates. The normal pH of saliva is about 6.3.
(b) The most prevalent bacterium in the mouth, streptococcus mutans, breaks down sugar and releases lactic acid (pKa = 3.86). If S. mutans has produced 10^-8 moles of lactic acid since your last swallow, what is the pH of your saliva? What would the pH be without the bicarbonate buffer? Assume that your mouth contains about 1 mL of saliva and that your saliva is flowing at a low rate.
(c) You take a drink of orange juice, and after you swallow, 0.5 mL remains in your mouth. What is the pH of your saliva if your mouth contains 1 mL of pure saliva, and if you model orange juice as 1.0 mM citric acid (pKa = 3.13; assume only one dissociation).
(d) Why do some toothpastes contain baking soda (sodium bicarbonate)?

Passage 2 (Questions 8–14)
In the first place, to make the poem or the novel the central concern of literary criticism has appeared to mean cutting it loose from its author and from the author’s particular hopes, fears, interests, conflicts, etc. A criticism so limited may seem bloodless and hollow.
In the second place, to emphasize the work seems to involve severing it from those who actually read it, and this severance may seem drastic and therefore disastrous. After all, literature is written to be read.
The formalist critic knows as well as anyone that poems and plays and novels are written as expressions of particular personalities and are written from all sorts of motives–for money, from a desire to express oneself, for the sake of a cause, etc. Moreover, the formalist critic knows as well as anyone that literary works are merely potential until they are read–that is, that they are re-created in the minds of actual readers, who vary enormously in their capabilities, their interests, their prejudices, their ideas. But the formalist critic is concerned primarily with the work itself. Speculation on the mental processes of the author takes the critic away from the work into biography and psychology. Such studies describe the process of composition, not the structure of the thing composed.
On the other hand, exploration of the various readings which the work has received also takes the critic away from the work into psychology and the history of taste. But such work, valuable and necessary as it may be, is to be distinguished from a criticism of the work itself. The formalist critic makes two assumptions: (1) that the relevant part of the author’s intention is what the author actually put into the work–that is, the critic assumes that the author’s intention as realized is the “intention” that counts. And (2) the formalist critic assumes an ideal reader–that is, instead of focusing on the varying spectrum of possible readings, the critic attempts to find a central point of reference from which to focus on the structure of the poem or novel.
There is no ideal reader, of course. But for the purpose of focusing on the poem rather than on the critic’s own reactions, it is a defensible strategy. (The alternatives are desperate: Either we say that one person’s reading is as good as another’s, and thus deny the possibility of any standard reading, or else we take the lowest common denominator of the various readings that have been made–that is, we frankly move from literary criticism into social psychology. To propose taking a consensus of the opinions of “qualified” readers is simply to split the ideal reader into a group of ideal readers.) As consequences of the distinction just referred to, the formalist critic rejects two popular tests for literary value. The first proves the value of the work from the author’s “sincerity” (or the intensity of the author’s feelings as he or she composed it). We discount also such tests as the intensity of the critic’s reaction.
A literary work is a document and as a document can be analyzed in terms of the forces that have produced it, or it may be manipulated as a force in its own right. It mirrors the past, it may influence the future. These facts it would be futile to deny, and I know of no critic who does deny them. But the reduction of a work of literature to its causes does not constitute literary criticism; nor does an estimate of its effects. Good literature is more than effective rhetoric applied to true ideas–even if we could agree upon a philosophical yardstick for measuring the truth of ideas and even if we could find some way that transcended nose counting for determining the effectiveness of the rhetoric.

The author of the passage probably rejects the use of biography and psychology in literary criticism because these disciplines:
Solution: The correct answer is D.
I thought B "assume that the author’s intention as realized is the only intention that counts." was the correct answer because in the passage it literally states that the authors intention REALIZED intention is the only intention that counts. The explanation given by AAMC doesnt really make much sense to me.

Assignment: What types of legal claims could Patty make against Cash Mart and Geoffrey?
Notes:
Introduction
In this assignment, you’ll need to decide whether Paula Plaintiff
has any legal claims arising from a series of unfortunate events.
After reading the scenario, answer the questions that follow,
making sure to fully explain the basis of your decision.
Paula Plaintiff is shopping at her favorite store, Cash Mart. She
is looking for a new laptop, but she can’t find one she likes.
Then, realizing that she is going to be late for an appointment,
she attempts to leave the store, walking very fast. However, before
she can leave, she is stopped by a security guard who accuses her
of shoplifting. Paula, who has taken nothing, denies any wrong
doing. The officer insists and takes Paula to a small room in the
back of the store. The guard tells Paula that if she attempts to
leave the room she will be arrested and sent to jail. At this
point, the guard leaves the room. Paula is scared and waits in the
room for over an hour until the manager comes in and apologizes and
tells Paula that she is free to go.
About this same time, Geoffrey Golfer is hitting golf balls in his
backyard. Geoffrey decides to break out his new driver and hits a
golf ball out of his backyard into the Cash Mart parking lot. The
golf ball hits Paula Plaintiff on the head and knocks her
unconscious just as she is leaving the store.
Instructions
In a 6–10 paragraph paper, answer the following questions:
What types of legal claims could Paula make against Cash Mart and
Geoffrey?
Consider the following:
What are the possible tort claims that Paula can make against Cash
Mart? Discuss the elements of the claim and how those elements
relate to the facts in the scenario.
Was Geoffrey negligent when he hit the golf ball that injured
Paula? Discuss the elements of negligence and use facts from the
scenario to support your decision.
If Paula files a negligence claim against Geoffrey will she file in
civil court or criminal court? Explain the difference between civil
court and criminal court.
