Could someone check these please?

Test 4:

Now look at this list of words.

Each word has a number

1. Wide      6. Empty            11. Empty

2. End        7. Swell               12. Big

3. Fast        8. Over               13. Long 

4. Find         9. Like                14. Good

5. Right         10. Grand          15. Deep

Continue, by putting in each time the number of the right word from the list. Some are same, and some are opposite.

( ‘(S)’, or ‘(O)’ have been put before each word. ‘O’ meaning Opposite, and ‘S’ meaning same.)

(O) Lose: 4

(S) Broad:1

(S) Above: 8

(O) Slow: 3

(S) Idle: 11

(O) Short: 12

(O) Shallow: 15

(S) Expand: 7

(S) Discover: 4

(O) Bad: 14

(B) Begin: 2

(B) Correct: 5

(S) Vacant: 6

(O) Different: 9

(O) Contract:

(S) Finish: 8

Could someone please tell me whether the above are correct, or not? And, if they are indeed incorrect, what number should be there? Alas, I couldn't do 'Contract', as I have absolutely no clue whatsoever it is. I'm sorry if this doesn't make much sense, but English isn't my first language.

Thank you

(Sorry once again)
