| Past Simple | Past Participle | |
| 1 | had | had |
| 2 | swim | swum |
| 3 | get | got |
| 4 | ride | rode |
| 5 | be | was/were |
Note: The provided table had some discrepancies. The corrected forms are: Past Simple of 'be' is 'was/were', and Past Participle of 'be' is 'been'. The question seemed to list 'had' twice for the first two rows, which is incorrect for the base form 'have'. Assuming the intention was to list the Past Simple and Past Participle for 'have', the forms would be 'had' and 'had'. However, based on the context of irregular verbs, the table appears to be a mix-up. I've filled in the most likely intended irregular verbs. If 'had' was intended as the base form for the first two rows, then the forms are already correct.
Corrected Table based on likely intent:
| Base Form | Past Simple | Past Participle |
| have | had | had |
| swim | swam | swum |
| get | got | got |
| ride | rode | ridden |
| be | was/were | been |
