Assertion:
A new media, that is growing by leaps and bounds these days, is the internet.
RI. People's communication skills have improved.
RII. Because science and technology is growing by leaps and bounds these days.
Answer: D
RI : "People's communication skills". This phrase implies "People's communicating ability", but not the media's. This is not a valid reason.
RII : Even if it is true that science has created this medium, it is people who accept it and make it popular. No reason is given in RII to explain why this medium is growing. Neither RI nor RII is a valid reason.
