10.
Human technology developed from the first stone tools about two and a half million years ago. At the beginning, the rate of development was slow. Hundreds of thousands of years passed without much change. Today, new technologies are reported daily on television and in newspapers.
This paragraph best supports the statement that
stone tools were not really technology.
stone tools were in use for two and a half million years
there is no way to know when stone tools first came into use.
In today's world, new technologies are constantly being developed
none of the latest technologies is as significant as the development of stone tools.
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
The last sentence states that new technologies are reported daily, and this implies that new technologies are being constantly developed. There is no support for choice a.With regard to choice b, stone tools were first used two and a half million years ago, but they were not neessarily in use all that time. Choice c is clearly wrong since the paragraph states when stone tools first came into use. Although some may agree that choice e is true, the author of the paragraph does not give support for this opinion.

  4. No gem is a pearl.

Only I and II follow
Only III and IV follow
Only either I or IV and either II or III follow
Only III and either I or IV follow
None of these
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:

III is the converse of the third premise and so it holds.

Some pearls are stones. Some stones are diamonds.

Since both the premises are particular, no definite conclusion follows.

Some stones are diamonds. No diamond is a gem.

Since one premise is particular and the other negative, the conclusion must be particular negative and should not contain the middle term. So, it follows that 'Some stones are not gems'.

However, I and IV involve the extreme terms of the three premises and form a complementary pair, Thus, either I or IV follows.
