The conclusion of World Trade Organization’s 11th biennial ministerial conference at Buenos Aires was worrisome. From an Indian standpoint, there was no loss as status quo continues in the most important issue: the right to continue the food security programme by using support prices. But the inability of the negotiators to reach even one substantive outcome suggests that WTO’s efficacy is under question. As a 164-country multilateral organisation dedicated to crafting rules of trade through consensus, WTO represents the optimal bet for developing countries such as India. Strengthening WTO is in India’s best interest.

 

Perhaps the biggest threat to WTO’s efficacy today is the attitude of the US. The world’s largest economy appears to have lost faith in the organisation and has begun to undermine one of its most successful segments, the dispute redressal mechanism. This is significant as the US has been directly involved in nearly half of all cases brought to WTO. Separately, large groups of countries decided to pursue negotiations on e-commerce, investment facilitation and removal of trade obstacles for medium and small scale industries. By itself this should not weaken WTO. But it comes at a time when there is growing frustration with gridlock at WTO.

 

India did well to defend its position on its food security programme. The envisaged reform package which will see a greater use of direct cash transfers to beneficiaries will be in sync with what developed countries do. But it’s important for India to enhance its efforts to reinvigorate WTO. In this context, India’s plan to organise a meeting of some countries early next year is a step in the right direction. WTO represents the best available platform to accommodate interests of a diverse set of nations. Therefore, India should be at the forefront of moves to fortify it.

 

Which of the following nation is keen to fortify its interest on WTO platform?

 

A) USA B) Japan
C) Russia D) India
 
Answer & Explanation Answer: D) India

It's nothing short of a revolution in how we eat, and it's getting closer every day. Yes, a lot of people are obese, and yes, the definition of "healthy eating" seems to change all the time. But in labs and research centres around the world, scientists are racing to match our genes and our taste buds, creating the perfect diet for each of us, a diet that will fight disease, increase longevity, boost physical and mental performance, and taste great to boot. As food scientist J.Bruce German says, "The foods we like the most will be the most healthy for us."

Is that going to be a great day, or what?

All this will come to pass, thanks to genomics, the science that maps and describes an individual's genetic code. In the future, personalized DNA chips will allow us to assess our own inherited predispositions for certain diseases, then adjust our diets accordingly. So, if you're at risk for heart disease, you won't just go on a generic low-fat diet. You'll eat foods with just the right amount and type of fat that's best for you. You'll even be able to track your metabolism day-to-day to determine what foods you should eat at any given time, for any given activity. "Since people differ in their genetics and metabolism, one diet won't fit all," says German.

As complex as all this sounds, it could turn out to be relatively simple.

What are scientists doing?

A) Racing in labs and research centres around the world B) Asking us to start dieting
C) Creating the perfect diet for us D) Try and make us taller
 
Answer & Explanation Answer: C) Creating the perfect diet for us

Q:

A subquery in an sql select statement.

Answer

A Subquery or Inner query or a Nested query is a query within another SQL query and embedded within the WHERE clause.


Subqueries are most frequently used with the SELECT statement. The basic syntax is as follows::


SELECT column_name [, column_name ]
FROM table1 [, table2 ]
WHERE column_name OPERATOR
(SELECT column_name [, column_name ]
FROM table1 [, table2 ]
[WHERE])



A subquery is used to return data that will be used in the main query as a condition to further restrict the data to be retrieved.


Subqueries can be used with the SELECT, INSERT, UPDATE, and DELETE statements along with the operators like =, <, >, >=, <=, IN, BETWEEN, etc.


 


There are a few rules that subqueries must follow −


 


1. Subqueries must be enclosed within parentheses.


2. A subquery can have only one column in the SELECT clause, unless multiple columns are in the main query for the subquery to compare its selected columns.


3. An ORDER BY command cannot be used in a subquery, although the main query can use an ORDER BY. The GROUP BY command can be used to perform the same function as the ORDER BY in a subquery.


4. Subqueries that return more than one row can only be used with multiple value operators such as the IN operator.


5. The SELECT list cannot include any references to values that evaluate to a BLOB, ARRAY, CLOB, or NCLOB.


6. A subquery cannot be immediately enclosed in a set function.


7. The BETWEEN operator cannot be used with a subquery. However, the BETWEEN operator can be used within the subquery.

Q:

Human gametes are produced by

A) Mitosis B) Meiosis
C) Replication D) None of the above
 
Answer & Explanation Answer: B) Meiosis

Explanation:

In humans all reproduction is sexual. It involves joining together haploid gamete cells from each parent with half the normal number of chromosomes to make a new cell containing both parents' genetic material. This is a diploid zygote. The cells from each parent that combine to form the zygote are called gametes.

 

Meiosis produces haploid gametes from a diploid parental cell.
