no place to report this but the english is wrong. Should be I walked and I ran
Yes, in the mobile app (at least the Android one) you can click the flag and write free text, not just tick "My answer should be accepted". Hopefully they will then see my explanation and understand why my answer should have been accepted.
Can the first verb be in -ka- form? The Tips & Notes say the first verb would be in -li- form and the subsequent verbs would be in -ka- form. What is the correct usage?
As a standalone, it should be 'nilitembea na nikakimbia'. The way it is now sounds like a continuation of a narration (like someone was describing other activities, then also listed walking and running - basically it would need context).
Typically the use of '-ka-' is for listing additional actions
why is 'nikatembea" past tense (I walked) and nikakimbia is present tense (I run)?
