Week 5

Question 1

Parallelism

Answer 1

And, or, neither, nor, not only/but also both, rather, not X, but Y, from X to Y = markers

Question 2

Rates and Work Problems

Answer 2

Use D/W = R * T
Remember T can be expressed as (W/R)
When given two machines, add their rates and resolve

Question 3

Age Problems

Answer 3

Write the problem exactly as stated.
If John is 3 years older than Billy
John = 3 + Billy

and in 6 years Billy will be 1/3 the age of John
( B+6 ) = ( 1/3 )( John + 6 )

Use both equations to solve.

Question 4

Argument Structure

Answer 4

C
P
X
B
When identifying the role of each statement, write the combo of letters, then look for the answer that follows the combo.

Question 5

Identifying assumptions

Answer 5

P = C (what must be true?)
The assumption is going to state some part of P tie it with some part of C. The biggest trap is to throw in totally different solutions, points that could relate but…no.

Question 6

Evaluating Assumptions

Answer 6

EV and look for 2 ways. If yes/no it will strengthen/weaken. All the other answer options either both strengthened or both weakened.

Question 7

Flaw of Assumption

Answer 7

FA and identify assumption and find the error in the logic

Question 8

Algebra

Answer 8

When you square a variable/square root…, remember that variable can be a positive or a negative.
(x-1)^2 = 400

Question 9

Algebra

Answer 9

special products

Question 10

Algebra: System of Inequalities?

Answer 10

Add ‘em
