2. Kanava on Busanissa.

The inessive case ending -ssa/-ssä indicates being inside or at a location. You use it in 'kanavassa', 'satamassa', and 'Busanissa' to show where the shark and the people are located. Add -ssa or -ssä to any noun based on vowel harmony to say something is inside or at that place, like 'talossa' (in the house) or 'koulussa' (at school).

3. Ihmiset auttoivat sitä.

The past tense is formed by adding the vowel -i- before the personal ending. You use 'auttoivat' and 'seisoivat' to describe actions that people completed in the past when they helped the shark. Take the verb stem, add -i-, and then add the plural ending -vat/-vät for 'they', such as 'he menivät' (they went) or 'he söivät' (they ate).

4. He käyttivät valoja ja tikkuja.

The partitive case is used for the object when the action is ongoing, incomplete, or when the object is plural. You use 'sitä' because helping is an ongoing process, and 'valoja' and 'tikkuja' because they are plural objects. Use the partitive ending -a/-ä or -ta/-tä for plural objects and for singular objects when the action is not a completed whole, like 'luen kirjaa' (I am reading a book) or 'ostan omenoita' (I am buying apples).

5. Heillä oli keltaiset paidat.

The adessive case ending -lla/-llä combined with the verb 'olla' expresses possession or wearing clothes. You use 'Heillä oli' to state that the people possessed or wore yellow shirts during the rescue. Put the owner in the adessive case and follow it with 'on' or 'oli' plus the object, like 'Minulla on koira' (I have a dog) or 'Hänellä oli hattu' (He had a hat).
