1Его маме 35. 2 У меня есть племянник . 3 Их дедушке 73. 4 У моего папы голубые глаза. 5 У их кузины есть жена На английском

Here is the English version of the task, followed by a clear, one-interpretation explanation.

Translations

1. His mother is 35.
2. I have a nephew.
3. Their grandfather is 73.
4. My father's eyes are blue.
5. Their cousin has a wife.

One coherent interpretation (with step-by-step reasoning)

• Assumption: “Their” in sentences 3 and 5 refers to the same young family described in sentence 2 (the nephew and his parent, who is the speaker’s sister).
• If the nephew’s grandfather is 73, that grandfather would be the parent of the nephew’s parent. In this interpretation, the nephew’s grandfather is the speaker’s father.
• Then:
  • The nephew’s mother (the speaker’s sister) is 35 (from sentence 1).
  • The nephew’s grandfather (the speaker’s father) is 73 (from sentence 3).
  • The speaker’s father has blue eyes (sentence 4).
  • The nephew’s cousin is a female who is married to another woman (sentence 5).

A simple family map (based on this interpretation)

• Father: 73 years old, blue eyes. He is the grandfather of the nephew.
• Sister: 35 years old. She is the mother of the nephew.
• Nephew: Child of the sister.
• Cousin: The nephew’s cousin is a woman who is married to a woman.

Notes

• There are multiple possible readings of “their” and who is who, since the statements don’t specify exact names or all generations. The interpretation above creates a consistent family relationship: your father is the nephew’s grandfather; your sister is the mother of the nephew; and the nephew has a female cousin who is married to another woman.
• If you want, I can show alternative interpretations or draw a simple diagram to visualize the relationships.
