Mixed text completion drill and practice
1. The book of Isaiah was so familiar to King that he had already begun ad-libbing when he quoted the prophet in looking to a future when every valley shall be _____(i)_______, every hill and mountain shall be made ______(ii)_______, the rough places will be made plain, and the ____(iii)_______ places will be made straight.
2. Leaning heavily on the Bible was not without risks to King Martin as that same Bible had been used to justify ____(i)_______. Yet even the ancient Israelites, God's own chosen people, were sinners, yet _______(ii)______ ones.
3.In drawing on the bedrock principles of Americans' secular scriptures, religious heritage and even the land itself, he stressed the ties that bound Americans, made equality obvious—even _______________.
A. Uncondign
B. Imperceptivable
C. Inevitable
D. Aocalyptic
E. Conspicuous
4.If the seemingly benevolent strategy was simply ______(I)________ to alloy for bigger government and more government intrusion into all of our lives as critic Jason is suggesting, then it was _____(II)_______.
Answers and explanation:
1. A,B,C
The clue for this question is 'the rough places will be made plain'. So, contrasting is the thing we need here. For the first blank, we need a word opposite of valley. Valley is normally low area. So, valley should be heightened.Exalted matches that one!!
For the second one, we need a word that should mean low. Ebb works!
For the last one, Crooked works!!
2.C,C
As using solely bible could be risky, there must be something bad things too that makes it risky. Inequality works for the first blank.
Yet is the pivot word for the next blank. Some positive word will work here. Only Redeemable suits(equitable does not work in context)!!
3.C
'Even' is the clue here. So more obvious is our prediction. Inevitable works which means unavoidable.
4. B,A
this is an example of causal relationship. "Seemingly" is pivot word here. It is used normally to contrast something. As benevolent is good thing, so something bad thing will work in this blank. Ruse means trick normally used for deceiving. So it looks like it is working.
Second blank should be deceptive.

Advanced quantitative strategy: plug in
Scoring higher requires different strategy. One should not stick with just algebraic approach, rather use different strategy, such as plug in. Today, I am going to explain how to use plug in method. Sometimes, when a quantitative math requires many steps , thus complicated, it is difficult to solve that math using traditional method. At that time plug in method is boon. You must be prepared to use different strategies in the quant section.
What is plug in method?
Plug in method means using smart numbers in math to solve the question efficiently. For instance, If there is variable in the question, you can replace the variable by any number. Using the numbers in lieu of the variables is easier and faster to solve that math.
When to use Plug in method:
Now lets see the math below:
So lets take Q=100 and t=10
so in 2002, the price is=10
in 2003. the price is =10+100% of 10=20
in 2004, the price is=20+100% of 20=40
that is p
so p=40
so in 2005, the price will be 40+100% of 40=80
So now we will put p=40 and t=10, and the answer choice that will yield 80 will be our answer!!
1. p + (1/2)(p-t) =40+(1/2)(40-10)=40+15=55 :: Eliminate it as we need 80
2. p + (1/2)((p-t)/t)p=40+(1/2)((40-10)/10)40=not 80=Eliminate it!
3. (p√p)/√t=(40√40)/√10=(40√(4*10))/√10=40*2*√10/√10=80=Bingo!
4. p² /4t=40² /4*10=1600/40=40=Elimiate it!
5. tp²=10*40²=16000=Eliminate it!
So 3 is our answer!!

When to use Plug in method:
1. You can use plug in method when there are variables in the question
2.You can use plug in method when there are variables in the answer choices
3. When the algebraic approaches requires many steps
4. You are not good in algebra or afraid of algebra
5. Algebraic method might require longer time, but considering the time limit in GRE you should use plug in method.
6. But mind it when the math is too simple, use algebraic approach.
Now lets see the math below:
1.At the end of each year, the value of a certain Champagne is Q percent more than its value one year earlier, where Q has the same value each year. If the value of the Champagne was t dollars on January 1, 2002, and p dollars on January 1, 2004, then in terms of p and t, what was the value of the Champagne, in dollars on January 1st, 2005?
1. p + (1/2)(p-t)
2. p + (1/2)((p-t)/t)p
3. (p√p)/√t
4. p² /4t
5. tp²
We have to plug in smart numbers: 10,100,100 etc.1. p + (1/2)(p-t)
2. p + (1/2)((p-t)/t)p
3. (p√p)/√t
4. p² /4t
5. tp²
So lets take Q=100 and t=10
so in 2002, the price is=10
in 2003. the price is =10+100% of 10=20
in 2004, the price is=20+100% of 20=40
that is p
so p=40
so in 2005, the price will be 40+100% of 40=80
So now we will put p=40 and t=10, and the answer choice that will yield 80 will be our answer!!
1. p + (1/2)(p-t) =40+(1/2)(40-10)=40+15=55 :: Eliminate it as we need 80
2. p + (1/2)((p-t)/t)p=40+(1/2)((40-10)/10)40=not 80=Eliminate it!
3. (p√p)/√t=(40√40)/√10=(40√(4*10))/√10=40*2*√10/√10=80=Bingo!
4. p² /4t=40² /4*10=1600/40=40=Elimiate it!
5. tp²=10*40²=16000=Eliminate it!
So 3 is our answer!!
