Select from each drop-down menu the option that creates the most accurate statement, given the information provided.

A. From cycle 17 to cycle 18 the amount of time spent focusing on celestial phenomena outside of Earth’s solar system___________.

Solar System Concentration in Cycle 17 = 5% ;  Other Concentration = 95% 
Solar System Concentration in Cycle 18 = 3% ;  Other Concentration = 98%

So we can see that the time spent focusing on phenomena outside Solar System is increases by 3% in Cycle 18.

A. decreased by < 5%
  B. increased by < 5%  
C. doubled
D. tripled

B. No category of phenomena experienced a change in proportional focus greater than a___________from cycle 17 to cycle 18.

Kindly Refer the image Below:
We can see that from cycle 17 to cycle 18:
Maximum increase = 200% (Extrasolar Planets)
Maximum decrease = -62% (Resolved Stellar Populations).
So Maximum change is 200% increase.

A. a 5 percentage point decrease
B. 50% decrease
C. 5 percentage point increase
  D. 200% increase

Sumi1010 · Answer

A. From cycle 17 to cycle 18 the amount of time spent focusing on celestial phenomena outside of Earth’s solar system___________.

% of time for Extrasolar planets in cycle 17 = 3
% of time for Extrasolar planets in cycle 18 = 9

Thus, the amount of time for extrasolar planets tripled ( since the duration of the cycle 17 and 18 remains same).

D tripled

B. No category of phenomena experienced a change in proportional focus  greater than  a___________from cycle 17 to cycle 18.

Cycle 17 Cycle 18 %change  (starting from Extrasolar, clockwise)
3 9 +200
5 5 nil
26 30 +15
4 4 nil
12 11 -8.3
12 12 nil
7 9 +28
6 4 -33
5 6 +20
13 5 - 61
2 2 nil
5 3 -40

Thus, 
A. a 5 percentage point decrease  - Resolved stellar Population has 8 percent point decrease. 
B. 50% decrease  - Resolved stellar Population decreased by 61 %  
C. 5 percentage point increase  - Extrasolar has 6 percent point increase. 
D. 200% increase -  Extrasolar tripled and hence has exactly 200% increase. 
There is no increase greater than 200%.

Hence,  D 200% increase.

A. From cycle 17 to cycle 18 the amount of time spent focusing on celestial phenomena outside of Earth’s solar system___________.

A. decreased by < 5%
B. increased by < 5%
C. doubled
D. tripled

answer : we have extrasolar % time spent in cycle 17 = 3%
we have % time spent in cycle 18 = 9%

so amount of time spent actually = 3*3% = 9% , thus tripled

so answer = D)tripled

B. No category of phenomena experienced a change in proportional focus greater than a___________from cycle 17 to cycle 18.

A. a 5 percentage point decrease
B. 50% decrease
C. 5 percentage point increase
D. 200% increase

here we do process of elimination

we have resolved stellar populations where there was 13- 5 = 8 percentage point decrease so a ) a 5 percentage point decrease is ruled out

for resolved stellar populations we have 13-5/13 *100 = 8/15*100 > 50% decrease so b)50% decrease is ruled out

for c. 5 percentage point increase - we have Extrasolar planets where increase is 9-3 = 6 percentage point increase , so c) 5 percentage point increase is also ruled out

d)200% increase : for extrasolar planets increase = 9-3/3 *100 = 200% and we can just see by obervation that no other phenomenon has greater than 200% increase , so answer is d) 200% increase

TarunKumar1234 · Answer

A. From cycle 17 to cycle 18 the amount of time spent focusing on celestial phenomena outside of Earth’s solar system___________.

Extra solar planets increased from 3% to 9%, so  it tripled. Ans. D.

A. decreased by < 5%
B. increased by < 5%
C. doubled
D. tripled

B. No category of phenomena experienced a change in proportional focus greater than a___________from cycle 17 to cycle 18.

No category of phenomena= Resolved stellar population grew from 13% in cycle 17 to 7% in cycle 18, which is decrease = (13-5)/13 ~50%
 And. B.

A. a 5 percentage point decrease
B. 50% decrease
C. 5 percentage point increase
D. 200% increase

OA has been updated now, Its B for first blank and D for the second one.

Sumi1010 ,  Deepakjhamb  Nice catch on second one but missed the first one,  rocky620  Excellent work done 10/10.

Folks I will post new questions on Monday at sharp 8 am Pacific, Points table with today's update will be posted soon and OE will also be posted.

Good Luck
