Doubt Clearance Thread: UPSC 2021

"When in doubt, observe and ask questions. When certain, observe at length and ask many more questions."

Created this thread as a one stop solution for all members so that all the doubts wherein any conceptual clarification is required can be solved here.

Now if a question comes in UPSC asking if ministers can be made a part of parliamentary committees. What do we consider?

First, such a statement is unlikely. 

Even if they ask, "Ministers can be made part of Parliamentary Committee" - then by itself this statement is correct. 

The statement would be wrong if it is framed in the following way - 

1. Union Ministers are members of all parliamentary committees.

2. Union Ministers are defacto members of all parliamentary committees. 

Hope this helps.

I read that GSLV are used to transfer satellites into GTO only.

However, I had a doubt that Since Chandrayaan and Gaganyaan used GSLV MK3 which are supposed to be LEO (Lower Earth Orbit) Missions, then I mean that isn't it becomes that GSLV can be used for LEO as well and hence it can carry out missions other wise carried out by PSLV as well.

And if it's true, then what exactly remains the difference between PSLV and GSLV. Because, as far as I know, the difference is only due to capacity (PSLV has lower capacity) and PSLV can be used in GTO and LEO missions as well. Now if GSLV can be used for LEO missions as well, then only difference will be due to capacity.

Can someone please clarify, confused a lot when I read about LV used in Chandrayaan and Gaganyaan missions.

@Capedcrusader I read that GSLV are used to transfer satellites into GTO only.

Where did you read that? I don't think there's anything like that. The difference lies in their fuel and capacity. 

PSLV can carry satellites up to a total weight of 2000 kgs into space and reach up to an altitude of 600-900 km. GSLV can carry weight up to 5000 kgs and reach up to 36,000 km.



When the weight and distance, either is high..we will use GSLV. 
If weight is very low, even if the distance is large, we might use PSLV

just remember these two lines as said by@PhoenixD 

When the weight and distance, either is high..we will use GSLV. 

If weight is very low, even if the distance is large, we might use PSLV "

After that follow the timeline of launch. chronology

Hello! A national emergency is declared under Article 352. Articles 358 and 359 describe the effects of a national emergency on our fundamental rights. 


I hope this helps.

Is it some test series Question? What exactly by forming boundary it means? All 4 are transboundary rivers.

Observe the figures all four are trans-boundry rivers......

But, Chenab is crossing the border and didn't play any role in deciding the boundry between India and the other farzi country.

How ever Jhelum Ravi and sutlaj basins are are part of deciding the boundry may be a few kilometres. 

Hence. 

Ignore such type of questions....... This the reason why making a good test series not an easy task......

Gold is imported. When its price goes up, we spend more foreign exchange to buy it. So exclude option 3. 

What is the answer given?

Ignore the Question. Poorly framed in my opinion.
