i have seen most of your answers and i found following mistakes.

*when we move from international date line (west to east) one seems to gain an extra day.

*yes duck sound produce echo.

*pakistan is situated on proximity to the tropic of cancer, so the answer is none.

*the largest desert is SAHARA desert (area 8,400,000 sq.km)

other are austrlian desert(1,550,000 sq.km)
arabian desert(1,300,000 sq.km)
gobi desert(1,040,000 sq.km)
kalahari desert(520,000 sq.km)

sonoran desert(310,000)
namib desert(310,000)
kara desert(270,000)
thar desert(260,000 sq.km)

sis I had asked largest SAND desert, that is Rab Ul Khali, in saudi arabia. and coldest desert is GOBI.
duck sound does not produce echo, as much as I have read in books.
Dateline MCQ is tricky, double check it

sorry to say that i have provided you the detail of desert and again you are saying rab-ul-khali desert. . tell me the source from where you have read that rab-ul-khali is the largest desert. i think geo need to change the figures now!

i know dateline wala tricky ha. but mujhey geo parhaty kae arsa guzar gaya ha and what i said is absolutly right.bcoz being a geographer i told you with full responsibility.


janab mane bhi research parhi thi 2004 ma jo america ma hue thi us ma saaf likha tha that quack of duck produce echo.


if your mcqs answers are right then give the link i will check it myself.bcoz i am sure 100./. that i am right.

sand and rocky deserts are different.generally said that Sahara is largest desert but largest sand desert is that which I have mentioned here. if not than prove me wrong. Do you agree with me that penguins are also found in deserts? yes, they are. search.

about dateline you are right

and quack matter is closed if you provide the magazine link that you have mentioned.

siraj, did you mention in mcq the word (sand)? you asked for largest desert and i gave you the right information.

plz are you further confusing us. plz clearly mention your questions and their options so that we can give you the right answers.

i will not agree with you siraj on any mcq,unless i will not search myself.

if i had asked largest desert, than the answer was sahara.

and if you feel that my MCQs are confusing you than plz suggest some MCQs from my posted ones, so that I can clear your confusion. it is a humble request. Though I am not expert in art of making MCQs, yet I try my best. and even I borrow some MCQs from net and books without confirmation. please sis you are whole heartedly welcome.

attempt new ones, i am sure, you will do above 60%, and plz also suggest defective MCQs if you find some.
thanx for your feedback

Duck's quack
"A duck's quack doesn't echo" is a much-quoted scientific myth. The truth is that a duck's quack does, in fact, echo; however, it may be difficult to hear. This myth was first debunked by the Acoustics Research Centre at the University of Salford in 2003 as part of the British Association's Festival of Science. It was also featured in one of the earlier episodes of the popular Discovery Channel television show MythBusters. The actual reason for the myth is that a quack is a quiet and fading sound which produces faint echoes.
