To complete this task, you need to select the correct form of the words in bold so that they fit grammatically and lexically into the context. Let's go through each question and identify the correct answer.

1. were chosen / have been chosen / chose
   The sentence is in a formal letter context and indicates that the action has already occurred. The correct choice is "have been chosen" because it suggests that the selection process is recent and relevant to the present context of the letter.

2. takes / will take / took
   The event is scheduled for a future date, March 19th. Therefore, the future tense is appropriate. The correct choice is "will take."

3. is beginning / begins / will begin
   The registration time is a scheduled event in the future, so the simple present tense is used for scheduled events. The correct choice is "begins."

4. get / to get / getting
   The structure "ought to" is used to give advice or recommendation and is followed by the base form of the verb. The correct choice is "to get."

5. aren’t allowed / allowed / don’t allow
   This is a passive construction indicating that calculators are not permitted. The correct choice is "aren’t allowed."

6. be keeping / kept / be kept
   This sentence also requires a passive construction to indicate that items must be placed under the seat. The correct choice is "be kept."

7. are forbidden / were forbidden / forbade
   The rule is currently in effect and is expressed in the present tense passive voice. The correct choice is "are forbidden."

8. needn’t / didn’t need / won’t need
   The context suggests a future necessity. The correct choice is "needn’t" (short for "need not") as it indicates you do not have to respond unless unable to attend.

9. congratulate / congratulating / to congratulate
   The sentence expresses intention or purpose, which typically uses the infinitive form. The correct choice is "to congratulate."

10. see / seeing / sees
    The phrase "look forward to" is followed by a gerund. The correct choice is "seeing."

By selecting the correct forms, the completed paragraph reads as follows:

Dear Mr Barnes,
I am writing to you because you have been chosen as one of the contestants in our yearly Maths competition which will take place on March 19th at the Wilbury Town Hall. Can you believe it? It is a great opportunity and you must be very excited! I want to let you know that registration begins at 8 am so you ought to get to the Town Hall before 7 am so you’ll have lots of time to get signed in. There are a few rules I should tell you about. Firstly, the use of calculators aren’t allowed during the competition. Secondly, all pens, pencils and papers must be kept under your seat. Finally, you mustn’t have a mobile phone or laptop with you when you arrive for the competition as they are forbidden by the organisers. You needn’t respond to this letter unless you are unable to attend. Once again, I would like to congratulate you on having been picked for the competition. Until then, we look forward to seeing you on March 19th at 7 o’clock.

Yours sincerely,
Peter Caplin (Wilbury Town Council Secretary)
