Dear invisible man

Just one correction

1. The question was about absorption of infrared radiations of sun not ultraviolet ones.
The question is right but key is wrong

Infrared IR radiations of sun are absorbed by green house gases, which include CO2 and water vapors.
However, the key provided by commission makes the correct choice as CO2 only.
Hence key is wrong, anyone can confirm this question.

One question in English was about,
Farm house was so isolated that they had to generate repeat generate their own electricity.......
One of guys said current is the right choice
No dear...
Right choice is power
Because neither supply nor grid are generated.
An electrical generator generates power, it does not generate supply.
The power is product of current and voltage.
Current is wrong because, none of you have ever heard you of current station. These are called power stations.

So power is right.

Again key is wrong and I hope paper setter was not an electrical engineer, had he been so, his degree might have been cancelled.

These are not mere mistakes but blunders.

@ Sikandar Bozdar

Yes, water vapours as well as CO2 absorb infrared radiations.

HYDERABAD: The recently held screening test of the combined competitive exams, conducted by the Sindh Public Service Commission (SPSC), has stirred a controversy for the board.
The candidates who sat for the test fear many of them will fail to make it to the second stage of the exams — the written test — owing to mistakes in the question paper.
As many as 24,442 candidates were issued admit cards for the December 28 test. According to SPSC controller Hadi Bux Kalhoro, only around 18,000 appeared in the test, which was held simultaneously in three centres in Hyderabad, Sukkur and Karachi. A total of 182 posts, including 136 of BPS-17 and 46 of BPS-16, are up for grabs.

Controversy
Several of the 100 MCQs in the screening test had mistakes, the candidates alleged. They claim that a large number of candidates who scored 50 or more marks will be most affected as they would not be able to accrue the minimum 60 marks, required to qualify for the written test.
“There were at least 15 questions with wrong answers,” alleged Asif Ali, who met the SPSC officials on Wednesday to submit complaints and recommendations on behalf of around a 100 candidates.
For example, the answer key of a question asking in which part of the atmosphere the commercial flights usually fly is given as ‘troposphere’. But the correct answer for this question is supposed to be ‘stratosphere’. Another key wrongly puts the spiral galaxy as the largest in the universe. According to Ali, another mistake is the use of the term, Doppler MRI machine, because magnetic resonance imagery is a completely different system from the Doppler technology. Another candidate, who did not want to be identified because he is a government servant, pointed out that Mirikot has been mentioned as the small fort enclosure in Ranikot fort in Jamshoro. Whereas, the correct answer was that both the Mirikot and Shergarh, which was also given as an option, are regarded as small enclosures in the historic fort.
SPSC sources say that the screening test was introduced as an additional test to ensure that the candidates with good knowledge of the written test’s subjects qualify for the exam. The written exam comprises six compulsory subjects totaling 700 marks, including a viva voce with 250 marks, and three optional subjects worth 150 marks each.
In a press statement issued on Tuesday, the SPSC admitted human error, putting it at around one or two per cent. “The candidates are assured that the margin of error will not affect their overall result,” read the statement issued by the controller.
A senior official of the SPSC, who sought anonymity, admitted to The Express Tribune that there were typing mistakes. “The chairperson has directed the members to sort out this issue. Benefit in terms of marks will be given to the candidates.”
The candidates’ delegation met the SPSC chairperson, Dr Agha Rafiq Ahmed, and controller Hadi Bux Kalhoro. They asked them to cancel the screening test, allowing all candidates to take the written tests and reduce the minimum passing marks to 40 instead of 60, or give at least 10 more marks to each candidate.
“They assured us that the candidates will be compensated but didn’t exactly say how,” said Mujtaba Samejo, who met the officials along with Ali. They warned the officials of court proceedings if the SPSC did not address their concerns.

yes mistakenly I typed UV, it is IR ,my point is that key is wrong, IR absorption by green house effect is follows By their percentage contribution to the greenhouse effect on Earth the four major gases are:

water vapor, 36–70%
carbon dioxide, 9–26%
methane, 4–9%
ozone, 3–7%
water vapors play major role. all option given in the answer are correct,but best choice is water vapor not CO2. SPSC is having their own homely science.

@ Ariz Ahmad
Dear, I also mentioned the same thing. Both CO2 and water vapours.
I chose this option, but key is wrong.

@invisible man
Dear, when water vapor and CO2 are in one option, this becomes best choice, both vapors and co2

Dear,
I'm not giving relaxation to examiner. Definitely he had done mistakes in a few question (a few means a few). Neither it affected our "over all result", nor we should multiply other 95% right questions to zero and bring forward the conclusion that the whole paper was full of flaws. You are right that examiner should be held accountable. But saying "makeshift kind of test" is a big conclusion from smaller percentage of mistakes, you come up with. Hope you got my point.

Dear,
You are right we should stand by our fellows in their rightful demands. Bringing passing percentage to 40% is not rightful demand it would be injustice to those who got lower than 40%. I demand:

1. That the answer keys should be corrected.
2. That for extra marks should be given for wrong questions (that are 2 or 3).
3. That the questions with 2 option right should be given right whoever tick any one of those options.

So that our other eligible brothers may get a chance to be the part of written CCE-2013.

@Ali Sikandar

Dear, there are about 10-15 questions, which are either wrong or have wrong keys.

So its not 95% right

10-15 mistakes in a competitive exam question paper are not easy to swallow, nor one can brush aside such a blunder.

This test is like a knockout round, where you either make it or you don't, because number of marks obtained doesn't matter. I have passed with 52, it would not make a difference, if I get 60 marks or so.

Think of those who got 40-49

Such mistakes must not be repeated and as of now, and all candidates must be awarded marks equivalent the number of such wrong questions. It is a standard practice even followed by NTS.

Why should candidates suffer for the mistakes of an ill-knowledgeable examiner?

This is no joke, its a competitive exam for heaven's sake.

Saying 10-15 mistakes is an exaggeration. If the case is so, than grace marks should be given. I'm not asking you to easily swallow this all. But saying the whole test, a joke or invalid is also injustice to those who got success.

Dear Ali Sikandar

I have myself passed this test, but passing is secondary. The primary issue is setting matters of the commission straight.

10-15 mistakes is not an exaggeration, its the fact. I have myself posted 12 questions, out of which, 10 are confirmed wrong, the rest are mistakes in keys.

Some questions were pointed out by other candidates, like nanga parbat incident and commercial jets flying in lower stratosphere. You can confirm these and other questions by yourself.

Nangaparbat, troposphere, IR radiations, curved railway tracks, airship Hindenburg, largest galaxy, father of rocketry, and many other questions are confirmed as wrong.

We may leave the dubious questions but how can we deny the questions that may easily be researched on internet and from other sources.
