Part 1: Circle the word that does not have the same sound.

#### Words:
at, sad, had, shut
ash, glad, sat, mask

#### Step-by-Step Solution:

1. Group 1: at, sad, had, shut
- at: /æt/ (short "a" sound)
- sad: /sæd/ (short "a" sound)
- had: /hæd/ (short "a" sound)
- shut: /ʃʌt/ (short "u" sound)

- All words except "shut" have the short "a" sound (/æ/). The word "shut" has a different sound (/ʌ/).

Outlier: shut

2. Group 2: ash, glad, sat, mask
- ash: /æʃ/ (short "a" sound)
- glad: /ɡlæd/ (short "a" sound)
- sat: /sæt/ (short "a" sound)
- mask: /mɑːsk/ (long "a" sound)

- All words except "mask" have the short "a" sound (/æ/). The word "mask" has a long "a" sound (/ɑː/).

Outlier: mask

Part 2: Circle the word that does not have the same sound.

#### Words:
accident, racing, icicle, inside
civil, excite, city, excite

#### Step-by-Step Solution:

1. Group 3: accident, racing, icicle, inside
- accident: /ˈæksɪdənt/ (short "i" sound in "cident")
- racing: /ˈreɪsɪŋ/ (long "a" sound in "ra-")
- icicle: /ˈaɪsɪkəl/ (long "i" sound in "i-")
- inside: /ˌɪnˈsaɪd/ (long "i" sound in "in-")

- All words except "accident" have a long vowel sound. The word "accident" has a short "i" sound.

Outlier: accident

2. Group 4: civil, excite, city, excite
- civil: /ˈsɪvəl/ (short "i" sound)
- excite: /ɪkˈsaɪt/ (long "i" sound in "i-")
- city: /ˈsɪti/ (short "i" sound)
- excite: /ɪkˈsaɪt/ (long "i" sound in "i-")

- All words except "civil" and "city" have a long "i" sound. However, since there are two words with the same sound ("excite"), we focus on the one that stands out differently. The words "civil" and "city" both have a short "i" sound, but "civil" is the only one that starts with a short "i" sound.

Outlier: civil
