Step 1) Recognize that this sentence is unusually complex with too many commas.

Step 2) The phrase “in analyzing the data”–ask yourself WHO is analyzing the data/gathering the observations? The model or the parents?
Well, it’s the behavioral model that is analyzing the data (more specifically, the people behind the scientific experiment)

Step 3) Apply Framework #3. Since we know the -ING verb describes the first few words in the sentence “behavioral model”–we can FLIP the sentence like so:

“In analyzing the meaning of the data they gather from these observations, the behavioral model of child development recommends that parents pay attention to their child’s emotional sensitivity and attachment style can adjust their parenting style to encourage their child to be more independent.”

Step 4) OK, the sentence above in quotes looks a little weird especially in the area in red.

Try some of the other answer choices that might have a slightly different sentence structure from (A). Notice (C), (D), and (E) have a slightly different structure with “style and,” instead of “style, and”—so let’s try (C) and FLIP it.

Step 5) Let’s try (C)

“In analyzing the meaning of the data…, the behavioral model… recommends that parents pay attention to their child’s emotional sensitivity and attachment style and adjusting their parenting style to encourage their child to be more independent.”

“Adjusting” is off here. So looks like (C) is no good. Let’s try (D).

Step 6) (C) was no good. So Try (D)

“In analyzing the meaning of the data…, the behavioral model… recommends that parents pay attention to their child’s emotional sensitivity and attachment style and adjust their parenting style to encourage their child to be more independent.”

Looks good. But ask yourself if this makes sense.
“Adjust their parenting style”—adjust WHOSE parenting style? Obviously, it’s the parents’ parenting style.
So is it structured correctly? Well, yea–it’s consistent with the earlier part the sentence: “their child’s emotional sensitivity”

Read like this:
“Analyzing the meaning of the data gathered from these observations, the model recommends that parents pay attention to their [the parents'] child’s emotional sensitivity… and adjust their [the parents'] parenting style to encourage their [the parents'] child to be more indepedent.”

So yes, it is structured correctly. And it makes sense from a meaning perspective.

So the answer here looks like (D).

=================================================================================

Someone asked me about (B). Well, let’s take a look

(B): “…style, and they analyze the meaning of the data gathered from these observations in adjusting their parenting style to encourage their child to be more independent. ”

Remember, the underlined portion is the part that needs to be changed. The non-underlined portion is always unchanged–which means it’s always correct.

Look at the non-underlined portion: “their parenting style”—WHOSE parenting style? We mentioned before it’s the PARENTS’ parenting style.

Look at the underlined portion: “and they analyze the meaning of the data gathered from these observations”—WHO analyzed the meaning of the data? It’s the people who conducted the study.

So put these together:

“and they [the people who conducted the study] analyze the meaning of the data gathered from these observations in adjusting their [the parents'] parenting style to encourage their [the parents'] child to be more independent.”

Notice that from a meaning perspective, the references to “they/their” are INCONSISTENT.

From a structural perspective, “they/their” must refer to the same thing. If you want to refer to two different things in two different parts of the sentence, then you have to structure the sentence differently.

But the way the sentence looks, it appears there is inconsistency here so (B) does not look right.

Note (D) does not have this dilemma. So that’s the reasoning behind (D).

Step 1) Translate Sentence
“The number of stamps that Kaye and Alberto had were in the ratio 5:3 respectively”
(K/A) = (5/3)
Cross Multiply:
(Equation #1): 5A = 3K

Step 2) Translate sentence
” After Kaye gave alberto 10 of her stamps, the ratio of the number Kaye had to the number Alberto had was 7:5.”
(K-10) / (A+10) = (7/5)
Cross Multiply

(Equation #2): 7(A+10) = 5(K-10)

Step 3) Translate Question
“As a result of this gift, Kaye had how many more stamps than Alberto”
This translates to: What is (end result of Kaye) – (end result of Alberto)?
(K-10) – (A+10) = ?

Step 4) Do we have enough info?
Before we answer the question, first we need to figure out if we have enough info to answer the question.
Well, you see to variables K and A. You also see two equations. Since # of equations = # of variables, you have enough information.

OK, now just simplify the second equation
7(A+10) = 5(K-10)
7A + 70 = 5K – 50
7A – 5K = -120

Step 5) Combine Equations That We Have To Solve for one of the variables
From Equation #1: 5A = 3K
5A – 3K = 0

Combine
7A – 5K = -120 –>Match K’s –>Multiply by 3 —>21A – 15K = -360
5A – 3K = 0 —>Match K’s —->Multiply by 5—->25A – 15K = 0

21A – 15K = -360
25A – 15K = 0

(21A – 25A) + (-15K – (-15K) = (-360 – 0)

-4A = -360
A = 90

Step 6) Use what we found to find the other variable

Since 5A = 3K, then 5(90) = 450 = 3K –> K = 150

Step 7) Now what’s the original question asking?
It’s asking:
(K-10) – (A+10) = ?

So (150-10) – (90 + 10 = 140 – 100 = 40
So 40 is the answer.

(A) which is a substance that promotes blood clotting, but not seriouslyinterfering
(B) a substance that promotes blood clotting, but not seriously interfering
(C) a substance that promotes blood clotting, but does not seriously interfere
(D) which is a substance to promote blood clotting, but does not seriouslyinterfere
(E) which is a substance that promotes blood clotting, but not a seriousinterference

Step 1) Identify this question as testing you on X&Y consistency framework. The keyword is “but”

Step 2) Notice the answer choice parts highlighted in red. To save time, you should be scanning these answer choices to find the pairs that match up.

Notice in (A) “promotes” does not go with “interfering”
(B) “promotes” does not go with “interfering”
(C) looks good
(D) “to promote” does not go with “interfere” (you need the word “to” again)
(E) “promotes” does not go with “interference”

So really, answer (C) is the only one that is possibly correct. Notice I didn’t even spend the time to reason through what makes sense and what doesn’t. I simply scanned the answer choices and found only one possibility that could potentially be the answer.

You could have answered this question in less than 10-15 seconds using this method. Of course it helps to go through some of the “does this make sense” thinking. But it’s also good exercise to try to answer questions in as little time as possible.
