Problem Analysis

We have four boys named Michael, John, Serge, and Frank who have arrived for a competition from four different countries: the United States, England, France, and Canada. We need to determine which boy is from which country based on the given clues.

Clues:

1. Frank and Michael are not from the United States. 2. John and Serge have already met a resident of Canada. 3. The person who flew from France is neither John nor Frank. 4. The boys from England and France solved all the problems with Michael.

Solution

Let's analyze the clues one by one to determine the country each boy is from.

Clue 1: Frank and Michael are not from the United States. This clue tells us that both Frank and Michael are not from the United States. We don't have any information about the other boys yet.

Clue 2: John and Serge have already met a resident of Canada. This clue tells us that John and Serge have already met someone from Canada. This means that John and Serge cannot be from Canada themselves. We still don't have any information about the other boys.

Clue 3: The person who flew from France is neither John nor Frank. This clue tells us that neither John nor Frank flew from France. This means that the person who flew from France must be either Michael or Serge. We still don't have any information about the other boys.

Clue 4: The boys from England and France solved all the problems with Michael. This clue tells us that the boys from England and France solved all the problems with Michael. This means that Michael must be from either England or France. We still don't have any information about the other boys.

Based on the given clues, we can make the following deductions:

- Frank and Michael are not from the United States. - John and Serge have already met a resident of Canada. - The person who flew from France is neither John nor Frank. - The boys from England and France solved all the problems with Michael.

Solution Deductions:

- Frank and Michael are not from the United States. - John and Serge have already met a resident of Canada. - The person who flew from France is neither John nor Frank. - The boys from England and France solved all the problems with Michael. - Michael is from either England or France.

Now let's analyze the deductions to determine the country each boy is from.

Deduction 1: Frank and Michael are not from the United States. Since Michael is from either England or France, Frank cannot be from the United States. Therefore, Frank must be from Canada.

Deduction 2: John and Serge have already met a resident of Canada. Since Frank is from Canada, John and Serge must be from the United States and France (in some order). We still don't know the country of Michael.

Deduction 3: The person who flew from France is neither John nor Frank. Since John is from the United States, the person who flew from France must be Serge. Therefore, Michael must be from England.

Based on the deductions, we can determine the country each boy is from:

- Michael is from England. - John is from the United States. - Serge is from France. - Frank is from Canada.

Therefore, Michael is from England, John is from the United States, Serge is from France, and Frank is from Canada.

Answer

Based on the given clues, the boys are from the following countries: - Michael is from England. - John is from the United States. - Serge is from France. - Frank is from Canada.
