Hi Brent,

Awesome,


I understand now,

Is that a universal rule?

I like the door of my car bought in NY.(car)
I like the door of my car, bought in NY.(door)

what about these sentences

I like the door of the car that I bought in NY.(door/car?)
I like the door of the car, that I bought in NY.(door/car?)


Is there a way to make it more clear and not so subtle?

Thank you in advance,

When it comes to the English language, I'm hesitant to ever use the term "universal rule"

To minimize the potential of ambiguity, I (personally) try to place the modifier as close as possible to the noun it modifies.
(e.g., I like the car door I bought in NY). That said, here are my answers:

I like the door of the car that I bought in NY.(car)
I like the door of the car, that I bought in NY.(door)

Hi Brent,

Thank you,

I understand,

Hi Brent,

Could you please explain why C is correct?

The passage most strongly suggests that its author would agree with which of the following statements about clocks?

A) Before 1921 no one had designed a clock that used electricity to aid in its timekeeping functions.
B) Atomic clocks depend on the operation of mechanisms that were invented by William Shortt and first used in the Shortt clock.
C) No type of clock that keeps time more stably and accurately than a Shortt clock relies fundamentally on the operation of a pendulum.
D) Subtle changes in the earth's rotation slightly reduce the accuracy of all clocks used in observatories after 1921.
E) At least some mechanical clocks that do not have pendulums are almost identical to Shortt clocks in their mode of operation.

"ultimate pendulum clock, indeed the ultimate mechanical clock of any kind"

How do we know that no other pendulum clock exist that might be more accurate. Simply because this is the only type of pendulum clock that has ever existed?

Many students will misinterpret this question as asking "Which of the following answer choices MUST be true?"
This is not the case.
The question asks us to identify the statement that the AUTHOR would agree with.
This is a much different question.

The line "ultimate pendulum clock, indeed the ultimate mechanical clock of any kind" pretty much says it all.

Adding to this, we have the author comparing Shortt clocks with atomic clocks, and noting that Shortt clocks are nearly as accurate as the atomic clocks.
In fact, it seems that the only reason Shortt clocks are not quite as accurate as atomic clocks is due to tidal distortion.
Since any pendulum clock would suffer from this same distortion, it's reasonable to conclude that a clock that's more accurate than a Shortt clock wouldn't operate via a pendulum.

C is the best answer.

Cheers,
Brent

Hi Brent,

I was afraid of answer C since, it is just inferred that the atomic clock is more accurate, because the pendulum clock was measured against it. I know from my own knowledge that an atomic clock is the most precise timekeeping device, but if it is not stated in the passage I must refrain from involving my own knowledge in drawing conclusions from the passage.

Where in the passage I can find evidence that atomic clock "was known to keep time extremely precisely and reliably"?

The passage most strongly suggests that the study described in the third paragraph would not have been possible in the absence of

A) accurate information regarding the times at which high and low ocean tides occurred at various locations during 1984
B) comparative data regarding the use of Shortt clocks in observatories between 1921 and 1932
C) a non-Shortt clock that was known to keep time extremely precisely and reliably
D) an Innovative electric-power source that was not available in the 1920s and 1930s
E) optical data-transmission devices to communicate between the U.S. Naval Observatory and other research facilities

The accuracy of atomic clocks is evident in Pierre Boucheron's conclusion in the third paragraph.
"...he measured the Shortt clock's rate against the observatory's atomic clocks for a month. He found that it was stable to 200 microseconds a day over this period"

Boucheron can only draw this conclusion if it's the case that atomic clocks are extremely precisely and reliably.
In fact, the only way to tell whether a clock is accurate is to have access to a clock that is even more accurate.

Answer: C

Hi Brent,

I have a question about this passage from the Official GMATPREP:

https://gmatclub.com/forum/the-united-states-government-has-a-long-standing-policy-of-using-feder-156465.html

It can be inferred that the "ownership gap" (see underlined text) would be narrowed if which of the following were to occur?

(A) Minority entrepreneurs received a percentage of government contracts equal to that received by nonminority entrepreneurs.
(B) Middle- and high-income minority entrepreneurs gave more assistance to their low-income counterparts in the business community.
(C) Minority entrepreneurs hired a percentage of minority employees equal to the percentage of minority residents in their own communities.
(D) The percentage of self-employed minority persons rose to more than ten percent of all self-employed persons.
(E) Seventeen percent of all persons employed in small businesses were self-employed.

I know that the answer to the question derives from this sentence: " At the time, minorities(1) constituted seventeen percent of the nation's population(2), but only four percent of the nation's self-employed."

But I can't understand the numbers and the groups:

(1) What do the minorities mean(people from minorities who were self-employed or all people who are considered minorities, irrespective of their status(employed, self-employed, unemployed)
(2)The population of working people, or of all people?

It would be the best if you could give a numeric example which will reflect the statement "At the time, minorities(1) constituted seventeen percent of the nation's population(2), but only four percent of the nation's self-employed.". With the explanation about why the author sees that the GAP existed. And what must have been the sentence in order to make the statement and the numbers "WITHOUT THE GAP", A.K.A everything is fine, the numbers say that there is no discrimination?

Thank you in advance for your help Brent,

That sentence from the passage can be somewhat confusing. Here's another way to write it:
"At the time, minorities constituted 17% of the nation's population, but minorities constituted only 4% of the nation's self-employed population."

Here's a scenario that meets all of the given information:
At the time, the country's TOTAL population was 1000.
Among those 1000 people, 170 were minorities (so minorities constitute 17% of the total population)
Let's also say that, among those 1,000 people, 100 people are self-employed.
Among those 100 self-employed people, 4 people are minorities (so minorities constitute 4% of the self-employed people)

ASIDE: If there were complete equality among the people, minorities would constitute 17% of self-employed people (since minorities constitute 17% of the total population).

Does that help?

Cheers,
Brent

Hi Brent,

Ok, now I understand.

So in fully egalitarian society in terms of gender:
If there are 80% men and 20% women, so there must among all CEOs be 80% CEOs who are men and 20% CEOs who are women. In addition, there must also be among the taxi driver population 80% of taxi drivers who are men and 20% taxi drivers who are women. In addition, there must also be among the nurses' population 80% of nurses who are men and 20% nurses who are women. And such ration 1/4 must be in every category.

So in patriarchal and men's job vs women's job society:
If there are 80% men and 20% women, so there must among all CEOs be more than 80% of CEOs who are men and less than 20% of CEOs who are women. In addition, there must also be among the taxi drivers population more than 80% of taxi drivers who are men and less than 20% of taxi drivers who are women. And such ration 1/4 must be in every category. In addition, there must also be among the nurses' population less than 80% of nurses who are men and more than 20% of nurses who are women.

Do I have the right thought process?

Thank you in advance,

That's a great analysis!

Hi Brent,

Could you please explain why D is the correct choice. By process of elimination, I was left with A and D, and I chose D

It can be inferred from the passage that the author of the passage considers Allen's "discovery" (see highlighted text) to be

(A) already known to earlier historians
(B) based on a logical fallacy
(C) improbable but nevertheless convincing
(D) an unexplained, isolated fact
(E) a new, insightful observation

Question link: https://gmatclub.com/forum/colonial-historian-david-allen-s-intensive-st...

(A) There's nothing in the passage to suggest that this particular discovery (that Puritan clergy from East Anglia were less likely than Puritan ministers from western and northern England to return to England by 1660) was already known by early historians.
While other historians (Greven, Demos, Lockridge, Holmes) are mentioned in the passage, there is no statement to the effect that these historians knew about the "discovery."

(D) an unexplained, isolated fact
The passage says: We are not told in what way, if at all, this discovery illuminates historical understanding.
In other words, the discovery is unexplained

D is the best answer.

Cheers,
Brent

Hi Brent,

Thank you very much,

Now I see it indeed that there is no information in the passage,

Thank you for your helpful explanation,

sir,
can you help me with the summary of the following passage-

https://gmatclub.com/forum/jon-clark-s-study-of-the-effect-of-the-modernization-of-a-telephone-ex-88689.html

thank you,

Question link: https://gmatclub.com/forum/jon-clark-s-study-of-the-effect-of-the-modern...

Paragraph 1: Study helps examine 1) technological determinism and 2) social constructivism.
Paragraph 2: Clark (determinist) - technology shapes organization. Braverman (constructivist) - organization shapes technology.
Paragraph 3: Constructivists misrepresent determinist position
Paragraph 4: Clark refutes constructivist's misrepresentation through his study

Main idea: examine debate via the viewpoint of social constructivists

Hi Brent
Regarding the meteor stream passage, my answer choice was E. in the explanation you mentioned that for e the chronology is not correct. However for answer choice by ou mentioned that first part is from 1st paragraph 2nd part is from last paragraph n 3rd par is from middle paragraph. Can you help me to understand how to decide between two closely related answer choices?
gmat-admin's picture

In the passage, a model concerning meteor particles was created, and that new model went against conventional theories. After the model was created, the big question was "Is this new model correct? Yes, the Geminid data confirmed the new model.

Let's examine the two answer choices:

(B) Describing a new theoretical model and noting that it explains the nature of observations made of a particular natural phenomenon
This is perfect. Note that the model explains the nature of observations made (with regard to the Geminid data)

(E) Analyzing recent data derived from observations of an actual phenomenon and constructing a model to explain the data.
This answer choice suggests that scientists collected the Geminid data and THEN construct a model to explain that data. This is incorrect

Here's the discussion thread for this question: https://gmatclub.com/forum/a-meteor-stream-is-composed-of-dust-particles...

Please let me know if that helps.

Thanks Brent this explanation helps
