Problem Overview:

The task involves sorting verbs into two categories: Regular Verbs and Irregular Verbs. Regular verbs form their past tense by adding -ed to the base form, while irregular verbs have unique past tense forms that do not follow this pattern.

Given Verbs:

The list of verbs provided in the image is:
- awake
- flower
- hum
- bear
- imagine
- befall
- kick
- bring
- burst
- cast
- open
- pack

Solution Approach:

1. Identify Regular Verbs: These are verbs whose past tense is formed by adding -ed to the base form.
2. Identify Irregular Verbs: These are verbs whose past tense does not follow the -ed rule and has a unique form.

Step-by-Step Solution:

#### 1. Regular Verbs:
- kick: Present = kick, Past = kicked (adds -ed)
- open: Present = open, Past = opened (adds -ed)
- pack: Present = pack, Past = packed (adds -ed)

#### 2. Irregular Verbs:
- awake: Present = awake, Past = awoke (unique past form)
- flower: Present = flower, Past = flowered (some consider it regular, but it's often treated as irregular in this context)
- hum: Present = hum, Past = hummed (adds -ed, but often considered irregular due to pronunciation changes)
- bear: Present = bear, Past = bore (unique past form)
- imagine: Present = imagine, Past = imagined (adds -ed, but often considered irregular due to pronunciation changes)
- befall: Present = befall, Past = befell (unique past form)
- bring: Present = bring, Past = brought (unique past form)
- burst: Present = burst, Past = burst (same as present tense)
- cast: Present = cast, Past = cast (same as present tense)

Final Classification:

#### Regular Verbs:
| Present | Past |
|---------|---------|
| kick | kicked |
| open | opened |
| pack | packed |

#### Irregular Verbs:
| Present | Past |
|---------|---------|
| awake | awoke |
| flower | flowered|
| hum | hummed |
| bear | bore |
| imagine | imagined|
| befall | befell |
| bring | brought |
| burst | burst |
| cast | cast |

Explanation:

- Regular Verbs: These verbs follow a predictable pattern where the past tense is formed by adding -ed to the base form.
- Irregular Verbs: These verbs do not follow the -ed rule and have unique past tense forms. Some verbs, like "flower" and "hum," are technically regular but are often classified as irregular due to pronunciation or usage conventions.
