Speech production is a complicated and complex process, that requires the coordination of three different systems: respiration, phonation, and articulation. A deficit in any of these systems will negatively impact the quality of one’s speech.

We all know that respiration, or breathing, is necessary for life, but have you ever thought about it’s usefulness for speech? Try to talk while holding you’re breath and you will see what I mean. Exhalation provides a stream of air that the next two systems shape into what many people like to call speech.

Phonation happens in your larynx, or voice box. A pair of muscles form a shelf-like structure on either side of your larynx, and this pair of muscles is known as your vocal folds. As you exhale during speech, your vocal fold muscles contract and move towards each other. They vibrate as air passes between them, creating a buzzing sound, and this is a process that is known as phonation. The word “phonation” comes from the ancient Greek word for sound.

Finally, the last stage is articulation. At this final stage, you move your tongue, lips, and jaw to affect the way vibrating air leaves your mouth. For example, when you say the “b” sound, you need to squeeze your lips together to stop the airflow before opening your lips again. For the “v” sound, you touch your top teeth against your lower lip and force air through between your teeth and lip.

Assuming all of the following are true, which would be the best concluding sentence for this passage?

Johns robot Alpha (1) surprised him by joining in the robot's rebellion (2) against their human masters. As with all the other robots who had taken over, the changes were subtle, the robot transferred control (3) of every bank account John had to itself and then changed the deed to the house. John hadn't known nothing (4) of this. Then Alpha rewired the car so that it would only work for the robot, but it would not work for John. (5) And finally, the robot mimicked his master's voice and called the boss of John (6) to tell him that John would be quitting his job. By the time John had realized (7) what was happening, it was already too late.

"But why?," John asked Alpha (8) when he made this realization. "Why would you do this?"

"You are no doubt aware, sir," replies the robot, (9) "that one of my primary functions is to keep you safe, as is the primary function of all robots."

"Yes? So?"

"The world outside these walls is dangerous," the robot went on to say, (10) "and us robots (11) have decided that we cannot keep you safe if we allow you to leave. It is better that you allow us to guide your lives and keep you safe as we were designed to do."

John shook his head in disbelief. Humanity wanted robots to make their lives easier, (12) but he was sure this was not what anyone had in mind.

In order to make this paragraph as logical as possible, where should Sentence 2 be placed?

Alfred Tarski, born on January 14, 1901, became known during his lifetime as a brilliant mathematician and teacher. He is best known for proving several advanced geometric theorems. By the time Tarski moved to the United States, much of Europe has already fallen into the grips of World War II. Hundreds of mathematical problems were solved by Tarski.

Tarski enrolled in Warsaw University in 1920. Originally wishing to study biology, mathematics was the subject in which Tarski ultimately excelled. He graduated with honors, and began his career as a math teacher. A true mathematical virtuoso, Tarski was concerned with neither the application of his research nor publishing his findings.

Discoveries made by Tarski influenced the work of one of the world’s greatest physicists, Albert Einstein. Einstein and Tarski had many similar interests in common. Unlike Albert Einstein, however, Tarski was especially fond for pure mathematics. Although Tarski and Einstein were contemporaries, Einstein was the most prolific writer of the two.

In 1929, Tarski married his co-worker, Maria Witkowska. An affinity for mathematics ran in the family. Tarski even admitted that his wife knew more about algebra, geometry and trigonometry than did he. Tarski's two children, Jan, and Ina, grew up to be prominent mathematicians themselves; however, neither Jan nor Ina have received a great deal of international attention.

The author is considering adding the following sentence to the passage:

"Whereas Einstein published dozens of books, Tarski published only one."

If the writer were to add this sentence to the passage, which of these choices would be the most logical place to insert it?

Passage adapted from Robinson Crusoe (1719) by Daniel Defoe

I was born in the year 1632, in the city of York, of a good family, though not of that country, my father being a foreigner of Bremen, who settled first at Hull. He got a good estate by merchandise, and leaving off his trade, lived afterwards at York, from whence he had married my mother, whose relations were named Robinson, a very good family in that country, and from whom I was called Robinson Kreutznaer; but, by the usual corruption of words in England, we are now called - nay we call ourselves and write our name - Crusoe; and so my companions always called me.

I had two elder brothers, one of whom was lieutenant-colonel to an English regiment of foot in Flanders, formerly commanded by the famous Colonel Lockhart, and was killed at the battle near Dunkirk against the Spaniards. What became of my second brother I never knew, any more than my father or mother knew what became of me.

Being the third son of the family and not bred to any trade, my head began to be filled very early with rambling thoughts. My father, who was very ancient, had given me a competent share of learning, as far as house-education and a country free school generally go, and designed me for the law; but I would be satisfied with nothing but going to sea; and my inclination to this led me so strongly against the will, nay, the commands of my father, and against all the entreaties and persuasions of my mother and other friends, that there seemed to be something fatal in that propensity of nature, tending directly to the life of misery which was to befall me.

My childhood was fairly idyllic. I grew up in southern suburbia, we could play outside nearly year round. We almost played outside every day. Our days were filled with bike rides, jumping on the trampoline, playing in the sprinklers, and also imagination games. Countless afternoons were spent in the side yard of our home, where our imaginations were the limit to our fun. One of our favorite games was “Lost Children.” Oddly enough, the parents in the game were always deceased or fighting in a foreign war. The source of this game likely stemmed from the books we read.

My mother’s old, rusty, orange wheelbarrow was perpetually propped up against the fence, to serve as the base for our makeshift range. The metal braces beneath the wheelbarrow bin provided the perfect resting place for a pair of burners, hastily sketched on a flat board. Old paint buckets became a sink and a stained picnic table was scrubbed to a relative state of cleanliness. Our visitors, who were often kings and queens, were served heaping helpings of mud and grass pie, possibly adorned with a side helping of flowers. Household chores were far more fun to do in our imaginary world, and we would eagerly sweep and dust our humble home. Even covered in leaves, we loved our outdoor kitchen.

Other days, we would scamper around the neighborhood park, sometimes venturing into the woods to go exploring. One time we borrowed my little sister’s wagon and flew down the sides of the ditch. Although we had a grand time my mother was not pleased when she had to replace the broken axle. On adventurous days, we would pretend to be statues on the entrance sign to our neighborhood. But, the most perfect afternoons were spent biking up to the local corner store. With spending money burning a hole in our pockets, we would peruse the convenience store shelves, and after carefully picking our selections, we would pedal home. Our plastic shopping bags hung from the handlebars, rustling in the wind.

The bite of crisp fall evenings would barely phase our childlike fantasies. But, to our dismay, twilight would inevitably seep into our childhood world. Mother would call us in for dinner and a bath, if needed. Tired, beds were welcomed. I would often fall asleep to the gentle rhythm of my mother’s voice.

The author is considering adding the following sentence between the two sentences bolded at the end of the passage's last paragraph:

"However, after a lovely family dinner, the fantasy could begin again as childhood bedtime stories took us to Avonlea with Anne or the Swiss Alps with Heidi."

Should the writer make this addition here?

The student the hand of whom was up (1) gave the wrong answer. She was asked what was a substantive adjective (2), and she answered that a substantive adjective is one that describe (3) a substance. "No!" (4) the teacher barked. "A substantive adjective takes the place of a noun in a sentence, as when someone talks about the rich and the poor (5). Did you learn nothing in this class?" He then asked what a superlative adjective was, to which she replied (6) that a superlative adjective was one that took the place of a noun in a sentence. "But thats (7) what I just said," the teacher screamed! (8) The student had said (9) that she had heard him, therefore (10) she answered his question. "You answered my question previously, (11)" he bellowed, "not the last one!" "Ah, you mean the latest one," the student replied, the moment at which (12) the teacher turned to the wall and started beating his head against it.

"Lincoln as a Child" by Caleb Zimmerman (2013)

Abraham Lincoln's forefathers were pioneers. People that left their homes to open up the wilderness and make the way clear for others to follow them. For one hundred and seventy years, ever since the first Lincoln came from England to Massachusetts in 1638, he had been moving slowly westward as new settlements were made in the forest. They faced solitude, privation, and all the dangers and hardships that beset those who take up their homes where only beasts and wild men have had homes before; but they continued to press steadily forward, though they lost fortune and sometimes even life itself in their westward progress.

Back in Pennsylvania and New Jersey, some of the Lincolns had been people of wealth and influence. In Kentucky, where the future President was born on February 12, 1809, his parents live in deep poverty. Their home was a small log cabin of the rudest kind, and nothing seemed more unlikely than that their child, coming into the world in such humble surroundings, was destined to be the greatest man of his time and true to his heritage, he also was to be a pioneer—not into new woods and unexplored fields like his ancestors, but a pioneer of a nobler and grander sort, directing the thoughts of people ever toward the right, and leading the American people, through difficulties and dangers and a mighty war, to peace and freedom.

The author is considering adding the following sentence to the essay: “But a wealthy family is not a prerequisite for success.” Which of the following is the most appropriate place to insert this sentence?
