Answer:
The absolute superlative of the adjectives given is:
- Alta: Altísima.
- Buenos: Bonísimos, óptimos.
- Simpático: Simpatiquísimo.
- Viejas: Viejísimas.
- Grande: Grandísimo.
Step-by-step explanation:
In Spanish you can find two forms of superlative: a normal one that is usually formed by adding the word "más", which for the adjectives given could be:
- La más alta.
- Los más buenos.
- El más simpático.
- Las más viejas.
- El más grande.
and the absolute superlative that is regularly formed adding the ending "ísimo" to the adjective and removing the last letter of the adjective (in the case of singular adjectives) or the last two (in the case of plural adjectives).
