Final answer:
In French, 'tu' is used for informal situations, while 'vous' is used for formal situations. Whether to use 'tu' or 'vous' depends on the relationship between the speaker and the person or group being addressed. The choice is influenced by familiarity and formality.
Step-by-step explanation:
To determine whether to use 'tu' or 'vous' to address each person or group of people, you need to consider the level of formality and familiarity. 'Tu' is used for informal situations when speaking to close friends, family members, or children. 'Vous' is used for formal situations when speaking to someone you don't know well, authority figures or groups of people.
- Salut, ça va? - The correct form to use would depend on your relationship with the person you are addressing. If you are close friends, you can use 'tu'. If it's someone you just met or a formal setting, 'vous' would be appropriate.
- Bonjour, monsieur! - Since this is a formal address to a man, the correct form to use is 'vous'.
- Irène et Amélie, on va au café dimanche? - Since 'Irène et Amélie' is a group of people, the correct form to use is 'vous'.
- Paul et Alima, c'est mon père! - Since 'Paul et Alima' is a group of people, the correct form to use is 'vous'.
- Non madame Gervason, je dois aider ma copine. - Since 'madame Gervason' is an authority figure, the correct form to use is 'vous'.
- Oui, je veux bien, Diego. - Since 'Diego' is a friend or someone familiar, the correct form to use is 'tu'.
- Oui? Monsieur et madame Abdou? - Since 'Monsieur et madame Abdou' is a group of people, the correct form to use is 'vous'.
