1. Select the code which gives the name of countries beginning with U

SELECT name FROM bbc WHERE name BEGIN with C
SELECT name FROM bbc WHERE name LIKE '%C'
SELECT name FROM bbc WHERE name LIKE '%C%'
SELECT name FROM bbc WHERE name LIKE U
SELECT name FROM bbc WHERE name LIKE 'U%'

2. Select the code which shows just the population of United Kingdom?

SELECT name FROM bbc WHERE name Like 'United%'
SELECT name FROM bbc WHERE population = 'United Kingdom'
SELECT name, population FROM bbc WHERE name = 'United Kingdom'
SELECT population FROM bbc WHERE name = 'United Kingdom'
SELECT population FROM bbc WHERE name = United Kingdom

3. Select the answer which shows the problem with this SQL code:SELECT name FROM "bbc" WHERE population > '2000000'

Apostrophes should be used around 'bbc' instead of speech marks
There are apostrophes surrounding '2000000'
There are speech marks surrounding "bbc"
There are speech marks surrounding "bbc" and there is apostrophes surrounding '2000000'
The use of a WHERE function is incorrect

4. Select the result that would be obtained from the following code: SELECT name, population / 10 FROM bbc WHERE population < 10000
