Tambahan in case you don't know, verb itu kata kerja ya. biar mudah kerjainnya, cari aja di setiap nomor yang ada tambahan kata -ing, terus buat verb present, ilangin kata -ingnya, buat verb past, tambahin kata -ed (tapi ini gak selalu). jadi jawabannya,
2. chasing, chase, chased, mengejar
3. planting/sweeping, plant/sweep, planted/swept, menanam/menyapu
4. conducting, conduct, conducted, mengadakan
5. examining/buying, examine/buy, examined/bought, memeriksa/membeli
hope this helps!
