As part of a collaborative ten-year plan involving technology upgrades

Question

As part of a collaborative ten-year plan involving technology upgrades, program development, and remodeling, four art museums—in Country X: the Arts Institute, City Museum, and Blake Museum; and in Country Y: the Davis Institute—will be closed for remodeling, one at a time, during a continuous seven-year period. For three of the four successive closings (labeled Periods I, II, III, and IV), the duration is to be two calendar years each. Other than during the seven years of successive closings, none of the four museums is to be closed during the ten-year period.

The plan stipulates that during the seven-year remodeling, each museum, during its period of closure and only then, will lend just one of its collections to one of the other three museums; when it reopens, it will immediately get its loaned collection back. No other borrowing or lending of art works by the museums is to occur during the ten years.

KarishmaB · Accepted Answer

Given are the constraints:

Art - 2 yrs III/IV
City - 1 yr
Blake - 2 yrs (<= 20 works, 2 year borrowing only)
Davis - 2 yrs ( x Only Country X)

Question 1.

Suppose the Davis Institute lends its Bronze Age Sculptures collection and immediately following its two-year closure period reopens with a special exhibition of sculpture, including the Bronze Age Sculptures collection and another sculpture collection borrowed under the ten-year plan. Given this and the information in the tabs, for each of the following sequences of closings for Periods I, II, III, and IV, respectively, select Yes if the sequence is possible. Otherwise, select No.

Davis must borrow a sculpture collection after re-opening so it cannot close last. Arts has sculpture but only from country X artists. Davis will not borrow this. So Arts cannot go after Davis. Davis can borrow sculpture from City or Blake (both have)

Blake-Davis-Arts-City 
 Arts cannot go after Davis. 
  Select  No

Davis-City-Blake-Arts 
 Possible. 
  Select  Yes

City-Blake-Arts-Davis 
 Davis cannot go last. 
  Select  No

Question 2.

The Davis Institute's curator is contemplating a proposal to close the museum in Period I and then, in Periods II and III, to borrow a medieval collection and a sixteenth-century collection (one collection per period, and in either order). To determine which museum would lend the medieval collection, which one of the following would it most help the curator to know?

The above is the question and the bold portion tells us that II and III are collections and about the types too.
ShilpiAgnihotrii

Davis goes   at I. 
 Medieval collection is there at Arts and Blake so one   of   these would lend it in II or III periods. Arts can lend it in period III only while Blake can lend it in periods II or III. 
 But which one?

That the City Museum will be closed in Period II 
 Arts or Blake could be closed in period III and lend the medieval collection to Davis. No info on   who   will lend it.

That the Arts Institute will be closed in Period IV 
 Arts will be closed in period IV which means that Arts cannot lend its collection in period II or III.   Hence   Blake would need to lend it to Davis in period II or III. 
  Correct.

That the Davis Institute will lend its Medieval Tapestries collection to the Blake Museum in Period I 
 Who does Davis lend its collection is irrelevant.

That the City Museum will be open in Period III 
 This means Arts or Blake would be closed in period III. But which is it? No info.

That the Arts Institute will be open in Period II 
 We are already given this in constraints. No new info.

Question 3.

The Blake Museum wishes to borrow a collection that consists of the same type of artworks as does one or more of its own collections. For each of the following, select Yes if, given the information provided, the indicated collection could be loaned to the museum and would satisfy the museum's wish. Otherwise, select No.

Constraints of Blake (<= 20 works, 2 year borrowing only)

Sixteenth-Century Landscape Paintings from the Arts Institute 
 They are paintings and < 20 so acceptable. 
 Select  Yes

Paintings by Country Y Artists from the Davis Institute 
 They are paintings and < 20 so acceptable. 
  Select  Yes

Twentieth-Century Sculptures from the City Museum 
 Since City will close for 1 year, it will not accept anything from City. 
  Select  No

chetan2u · Answer

So much of info flowing, Let us try to pick the important points.
 Ten year plan :
The four museums will be closed for continuous 7 years, three museums for 2 years and one for 1 year.
Each museum when closed would give an item on loan for the period it is closed and then take it back immediately on opening.
 Constraints :
City museum will close for 1 year.
Arts Institute will close in III or IV, and surely that would be a 2 year period
The Blake Museum will borrow only collections of 20 works or less and accept loan collections for a full two-year period only. So does not take an item on loan from City museum. 
The Davis Institute, in Country Y, will not borrow collections explicitly devoted only to Country X artists
 Collections :
A table is then given of items.

Question 1:-
 
So, Davis closes and then the next one that would close will be a museum with sculptures. Hence it will be Blake or City. It will not be Arts as the sculptures there are explicitly devoted to country X artists. 
Blake-Davis-Arts-City....NO, neither Blake or City after Davis.
Davis-City-Blake-Arts...YES, City is immediately after Davis, and all constraints can be met.
City-Blake-Arts-Davis....NO, neither Blake or City after Davis.

Question 2:-
 
So D is I.
 II and III : one will be Medieval collection(M) and other 16th century collection(S).
Blake: Medieval Sculptures
Arts: Medieval and 16th century collection
City: 16th century collection

1.  That the City Museum will be closed in Period II 
It could be II and III:  Blake(M) and City(S)  or  Blake(M) and Arts(S)  or  Arts(M) and City(S) . Thus, it could be Blake or Arts

2.  That the Arts Institute will be closed in Period IV. 
So, only possibility for Medieval is Blake and 16th century is City.
 Sufficient to know M will come from Blake.

ShilpiAgnihotrii · Answer

Chetan, what is the meaning of this? pls elaborate.

So D is I.
 II and III : one will be Medieval collection(M) and other 16th century collection(S).

I understand D is I meaning we are assuming Davis to be closed in period I.
But what is II and III ? Why are we assuming II and III as collections ?? Pls clarify. thanks!

zoezhuyan · Answer

hi  chetan2u 
there is a sculpture in Arts institute, 
the 2nd one on the list.

so why Blake-Davis-Arts-City is incorrect? 
for me, it's totally OK

chetan2u · Answer

Hi

The constraint ‘ The Davis Institute, in Country Y, will not borrow collections explicitly devoted only to Country X artists’ does not allow Arts to be immediately after Davis as the only sculpture that Arts museum has is the one that talks of exclusively made by X country’s artists.

Hence NO

UDEMYtutorJackson · Answer

Question 1: 
 No  - Davis Institute can not borrow suclpture by Country X Artists
 Yes  - possible
 No  - Davis cant be last (otherwise not possible for the Davis Institute to borrow a sculpture collection)

Question 2: 
 medieval collection  -  can be from Arts Institute or Blake Museum
 sixteenth-century collection  - can be from Arts Institute or City Museum

Options:That the City Museum will be closed in Period II -  Not sufficient - medieval collection can come from either Arts Institute or Blake Museum That the Arts Institute will be closed in Period IV  -   Hence medieval collection has to come from Blake (Blake needs to be closed in Period 2 or 3 )  That the Davis Institute will lend its Medieval Tapestries collection to the Blake Museum in Period I -  Irrelevant That the City Museum will be open in Period III -  Not sufficient - City Museum Could be closed in Period 2 or open in Period 2  That the Arts Institute will be open in Period II -  Not sufficient - Arts Institute could be open or closed in Period 3

UDEMYtutorJackson · Answer

Question 3:

1.Blake Museum has collections of the following type - paintings and sculptures
2.Twentieth-Century Sculptures from the City Museum is a NO - because Blake only accepts collections for 2 years and City Museum closes only for 1 year
3.The other 2 collections mentioned are Yes, because they have <=20 Number of works and satisfy the time constraint and type requirement (Painting)

The Answer is 
YES
YES
NO

poojita42 · Answer

Question 3: 
I was confused for a while but finally came up with the answer with the following reasoning:

Blake Museum has  paintings  and  sculptures . 
 And Blake Museum accepts collections of only 20 or fewer for two years only.

Sixteenth-Century Landscape Paintings from the Arts Institute - Paintings, two years and fewer than 20.  Yes 
Paintings by Country Y Artists from the Davis Institute - Paintings, two years and fewer than 20.  Yes 
Twentieth-Century Sculptures from the City Museum - Sculpture,  one year , and fewer than 20.  No

vivekthesmarty · Answer

For three of the four successive closings (labeled Periods I, II, III, and IV), the duration is to be two calendar years each.

If the above statement is true, then how come Davis-City-Blake-Arts is a possible sequence? The above statement states that for 3 of the 4 successive closings, the duration should be two calendar years, which means City Museum either closes first or last. Let me know what am I missing here. Thanks!

KarishmaB  pls help.

KarishmaB · Answer

The "successive closings" are the four closings, not 3. The 4 closings happen successively, one after the other without interval for 7 years (2+1+2+2 or 2+2+1+2 or ... ). 
We are not given that the 3 of the 2 year closings happen successively.

iamTOPSHOT · Answer

KarishmaB  can you help with an explanation for the 2nd question?

surendrasaini1 · Answer

KarishmaB  Please help wih this doubt.
In question number 1, how could Option Davis-City-Blake-Arts be possible as per the constraint (2 year borrowing only).City is closed only for1 year and can lend only for 1 year.

KarishmaB · Answer

The answer is correct.

Note that Davis will LEND for 2 years because it closes for 2 years. But are we given that it cannot BORROW for 1 year? No. 
We are given that Blake borrows for 2 years only but no such constraint is there for Davis.

Note the question stem:
 Suppose the Davis Institute lends its Bronze Age Sculptures collection and  immediately following its two-year closure period reopens with a special exhibition of sculpture , including the Bronze Age Sculptures collection and another sculpture collection borrowed under the ten-year plan.

Immediately after re-opening the exhibition takes place. So it could easily be borrowing City's sculptures for 1 year.

bhavikachawla97 · Answer

How can we plan to attempt a question of this difficulty? This will consume time and chances of the answer being right under pressue also seems less. How should we plan to attempt these questions? guesswork and move on or to actually solve?

KarishmaB · Answer

The challenge of MSR is learning how to handle data and details. Yes it will consume time and you should be ready to devote about 8 mins to your MSR. Also, if you end up getting 2 MSR sets, then about 15 mins will go in that. So you will have about 2 mins per question for all other questions and that is the time you must aim to allocate other question types. If you are short on time, you can skip a particularly hard looking question of another type since that will be 1 independent question.

You cannot skip MSR since it means 3 back to back incorrect answers. So tell yourself that it is a non negotiable and once you do, see it all making sense.

KarishmaB · Answer

Given: will be closed for remodeling, one at a time, during a continuous seven-year period. For three of the four successive closings (labeled Periods I, II, III, and IV), the duration is to be two calendar years each.

Just means that of the 4 successive closings (it is given that they will close in a continuous 7 year period), 3 closings will be for 2 years and 1 will be for 1 year. Since the total period of closings is 7 years, it works.
So duration of closings could be:
2, 2, 2, 1
2, 1, 2, 2
1, 2, 2, 2
etc.

zaltinator · Answer

I approached the question by trying to make all combinations within the given constraints, which is very time consuming. How should I judge whether I need to make the combinations before hand, or whether I can be sure of answering questions with just handling questions and constraints one at a time?
