I Ce sont les fenêtres de l'appartement de madame Bernard ? sont les fenêtres de .. appartement. - Tu téléphones à .. fils sont lycéens ? - photos de Londres sont très belles. - . Non, ce directeur ? – Non, je téléphone à . fils. filles sont lycéennes aussi. ... ... de Paris sont aussi très belles. ... ​

"Ce sont les fenêtres de l'appartement de madame Bernard ?" signifie "Are these the windows of Mrs. Bernard's apartment?".
To answer this question, we need to identify the appropriate pronoun to introduce the correct noun (les fenêtres). In this case, the noun is "fenêtres," which is plural, and the pronoun that agrees with it is "ce." Therefore, we can rephrase the question as "Ce sont les fenêtres de l'appartement de madame Bernard ?"

To answer this question, we can use the sentence structure "Ce sont + definite article + noun + de + possessive pronoun + owner."

Now let's break down the sentence step by step:

1. "Ce sont" means "These are" or "Those are." In this case, we use "Ce sont" to refer to multiple windows.

2. "les" is the definite article for plural nouns, so we use it before "fenêtres" to mean "the windows."

3. "de l'appartement" means "of the apartment," where "de" is the preposition used to indicate possession.

4. "de madame Bernard" means "of Mrs. Bernard," where "de" is again the preposition used to indicate possession.

Therefore, the complete answer to the question "Ce sont les fenêtres de l'appartement de madame Bernard ?" would be "Oui, ce sont les fenêtres de l'appartement de madame Bernard." ("Yes, these are the windows of Mrs. Bernard's apartment.")

Moving on to the next part of the question: "Tu téléphones à .. fils sont lycéens ?" This translates to "Are you calling .. sons who are high school students?"

1. To answer this question, we need to identify the appropriate pronoun to introduce the correct noun, which is "fils" (sons). In this case, we can use "tes" (your) as the possessive pronoun to match the plural form of "fils."

2. We can rephrase the question as "Tu téléphones à tes fils qui sont lycéens ?" ("Are you calling your sons who are high school students?").

The complete answer to this question will depend on who the question is being asked to. For example:

- If the question is being asked to a person who has sons who are high school students, the answer would be something like "Oui, je téléphone à mes fils qui sont lycéens." ("Yes, I'm calling my sons who are high school students.")

- If the question is being asked to a person who does not have sons who are high school students, the answer would be something like "Non, je ne téléphone pas à mes fils. Mes filles sont lycéennes." ("No, I'm not calling my sons. My daughters are high school students.")

Moving on to the next part of the question: "Les photos de Londres sont très belles." This translates to "The photos of London are very beautiful."

This statement is complete and does not require any further explanation or answer.

Lastly, the question ends with: "Non, je téléphone à .. fils. Les filles sont lycéennes aussi." This means "No, I'm calling .. sons. The daughters are also high school students."

1. To answer this question, we again need to identify the appropriate pronoun to introduce the correct noun. In this case, we can use "mes" (my) as the possessive pronoun to match the plural form of "fils."

2. We can rephrase the answer as "Non, je téléphone à mes fils. Les filles sont lycéennes aussi." ("No, I'm calling my sons. The daughters are also high school students.")

This provides a complete and detailed answer to the question, taking into consideration the appropriate pronouns, possessive pronouns, and sentence structures.
