Boy Meets Girl

I saw her at the diner: Traci from my high school, whom I find aesthetically appealing.

Her vivacious personality makes her popular.

I checked her out surreptitiously, glanced at her discreetly out of the corner of my eye. 3

I was in a quandary. Should I cower in the corner or summon the fortitude to say hello?

I overcame my trepidation. “Anyone sitting here?” I pointed to the empty seat.

But she harangued me, “Who are you? What even is your name?” Darn, I thought, forgot to even introduce myself. Maybe I’m being too brash, brazen and audacious.

Looking down at my tousled shirt, I also noticed my appearance – unkempt, disheveled.

“But I’ll share my burger and my b-b-b-everage,” I stammered. “And what’s more, I’m adept at making you laugh.”

She laughed, irritation placated. I sat adjacent to her at the counter, avoiding an afternoon of solitude.

Strategies for Sentence Completions

of all the hard words but also present a great opportunity to boost your score with a few good strategies.

Tragically, the rock star was known for ______________ behavior, showing no restraint in his abuse of drugs and alcohol, right up until his untimely death.

Can you identify which word or phrase the blank needs to match? Underline it: no restraint unrestrained or even bad would be good initial guesses. You don’t have to write these, but look for a similar word in the answer choices. Rule 1: Underline key words the blank refers to. Rule 2: Anticipate Our example seemed easy until you see the choices: (A) intemperate (B) loquacious (C) magnanimous (D) laconic (E) mercenary Now would a good time to be honest with yourself. If you knew none of these words, skip the question and bank your time for the longer readings. Rule 3: – usually the last couple in each set – if you don’t know the words. There’s no point wasting time on a question that will come down to a guess. Your score will be determined mostly by the long readings. Give yourself enough time for those and go back to the hardest sentence completions at the end, if you have time. 6

“If you’ve been studying your word lists, you know loquacious means talkative and laconic means the opposite – quiet, taciturn, not talking much.” Since the question has nothing to do with the rock star’s speaking volume, cross these out. Your answer: ________? (Answers appear on p 167.) Rule 4: Actively eliminate the wrong choices and guess from the remaining ones, even if you are unsure of the answer. “Don’t panic if the SAT tries to overwhelm you with hard words. You may not know the meaning of four of the choices, but if the one word you do

Consider this example: The facial expressions of the islanders can be misleading – the people always seem to be smiling, but the cheerful exteriors often belie a personal history of ______________. (A) autonomy (B) wanderlust (C) turmoil (D) decadence (E) euphoria

Were you able to spot a word that works, even if you were unfamiliar with most of the other words? Now let’s examine a sentence with two blanks: Despite years of poverty and ___________, the (A) celebrity ... condemned (B) depression ... scorned (C) abundance ... praised (D) revelry ... detained (E) adversity ... acclaimed Pause at the comma and underline the words poverty and. Can you sense answer choice. Which three can you eliminate? Your answer? 7

Rule 5: Analyze one blank at a time to get a few quick cross outs. Note: the word in the blank isn’t random. It forwards or reverses another idea in the sentence. For example, in the “poverty” sentence above, the and suggests a continuation of poverty, while despite signals a reversal of being poor and disadvantaged. Rule 6: Look for Forwarding or Reversing signals like these: Forwarding Reversing and, also, furthermore, as, despite, however, although, in addition, because, but, though, while, not only, since , ; : nonetheless, whereas Even if you don’t see these exact words, try to get a sense of whether the blank continues or opposes another idea in the sentence. Notice how the punctuation symbols , ; and : can suggest a forwarding of meaning. Rule 7. Choose the better blank. Go after the blank you get a better feeling for, often the second blank in the sentence. For example: Comments intended as ___________ can actually cause insult and inflict pain, if uttered in a ___________ way. (A) benevolent ... conciliatory (C) innocuous ... belligerent (E) beneficial ... gregarious

(B) theoretical... friendly (D) derogatory ... hostile

Would something inflict pain if said in a friendly, conciliatory or gregarious way? Cross out A, B and E. You may be able to guess the right answer, even if you don’t know innocuous (harmless) or belligerent (hostile). Rule 8: When in doubt, use your ear.

If you forget all your rules on the test, don’t panic. Read the sentence five times, once with each answer choice filled in, and listen for the one that sounds best.

Insight

Start by rewriting the numbers in order: 6, 8, 10, 12, 14. Do you see the symmetry? The average must be 10, because the other numbers are evenly spaced above and below 10. Removing the average itself, 10, won’t change the average.

Averages

The average, or arithmetic mean, is one of three ways to describe the statistical center of a list. (The others, median and mode, are covered on pp. 104 - 105 below.) “Tyler, how much do you make at that job?”

“Why would removing the average not change the average, Professor David?” “Well, imagine you had an 85 test average in Algebra. What would happen if I dropped your lowest test grade?”

“My average would go up.”

“But if I were so cruel as to drop your highest grade, your average would go down. If I dropped a score of 85, right at your test average, your average would remain unchanged.”

Can you see why 500 is his average without having to work it out? Sometimes you will be asked to spot this type of symmetry within a group of numbers:

But you will usually need to find the average from the definition: the sum of the numbers divided by the number of numbers.

What number can be removed from the following list without changing the average: 6, 14, 8, 10, 12? 13

Practice: Find the average in each

Now multiply both sides by 5 to clear the fraction.

lettered list below. (A) 2, 11, -10 (B) 3, 8, -7, -12

So 86 + 93 + 91 + 82 + x = 90 x 5. Use your calculator to obtain:

(C) x, y

352 + x = 450

(D) m, n, p

Subtract 352 from each side; x = 98. What is the average daily salary for the work week below? Day Monday Tuesday Wednesday Thursday Friday

1. If the average of 7, 8, 9, and x is 10, what is the value of x?

Hereâ€™s a typical SAT problem: Annâ€™s four test grades are 86, 93, 91, and 82. What does she need to score on her fifth test to bring her average up to 90 for the five-test period?

2. The average of a, b and 3 equals 6. What is the average of a and b?

Solution: Think of the unknown grade as x, and set the sum of the grades over five equal to the average: 86 + 93 + 91 + 82 + x = 90 5

14

Total: The key to solving more advanced average problems is to work with underlying totals. Find the total by multiplying the average by the number of numbers. For example, suppose a player is averaging 10 points per game after 5 games this season. Then he or she has scored 5 x 10, or 50 total points. This illustrates a formula you haven’t learned in school. If you can remember the following phrase and how to use it, you will know how to solve two challenging types of SAT math problems: ANTs live in the DiRT.

How to use the ANT: After four algebra tests, Ann has an 88 average. What does she need to score on her fifth test to bring her average up to 90 for the five-test period? Solution: Almost the same as an earlier example, this one is best solved using the A x N = T formula. Let T1 be the total points so far on all four tests combined. Then T1 = 88 x 4 = 352. Now go back to the formula and let T2 be the desired total for a 90 average on 5 tests. Then T2 = 90 x 5, or 450. Finally, subtract the two totals to obtain the number of additional points she needs: T2 – T1 = 450 – 352 = 98. Compare the next two examples to see how the ANT formula is really the DiRT formula in disguise.

ANT stands for: Average times Number is Total. A x N = T. DiRT stands for: Distance is Rate times Time. D = R x T. 15

Solutions: 1.) Let D1 equal the D1 = 20 x 4 = 80 miles. Let D2 equal the distance for the second part of the trip; D2 = 30 x 6 = 180. So total distance is 80 + 180 = 260 miles. Finally, for the whole trip, the car drove 260 miles in 4 + 6 = 10 hours. 260 = r x 10 . The rate is 260 Ăˇ 10 = 26 mph. 2.) Let T1

1. A car returning from Tahoe in a blizzard drove at an average speed of 20 miles per hour for four hours, and then at 30 miles per hour for the next six hours. What was its average speed for the 10 hour trip?

4 games. T1 = 20 x 4 = 80 points. Now T2 = 30 x 6 = 180 points in the next 6 games combined. So the player scored 80 + 180 = 260 points in the whole 10 game season. 260 = avg. x 10, so his or her average is 26 points per game.
