Rationale
Complex disconnect hatch contains examples of a closed syllable.
Closed syllables are those that end in a consonant, resulting in a short vowel sound. In the word set "complex," "disconnect," and "hatch," each word ends with a consonant, demonstrating the closed syllable structure.
A) Complex disconnect hatch
This option includes three words, all of which are closed syllables. "Complex" ends with the consonant 'x,' "disconnect" ends with 't,' and "hatch" ends with 'ch,' confirming that each syllable closes with a consonant, thus producing short vowel sounds.
B) Dirty nurse perfume
In this set, "dirty" has a closed syllable, but "nurse" and "perfume" do not. "Nurse" ends with a vowel sound, and "perfume" ends with a silent 'e,' which makes it an open syllable. Therefore, not all words in this set exemplify closed syllables.
C) Because domain flour
Here, "because" and "domain" both end in a vowel sound, making them open syllables. "Flour," although it has a vowel followed by a consonant, does not follow the closed syllable rule since the vowel sound is long. Thus, this set fails to represent closed syllables effectively.
D) Cargo iodine radio
In this group, "cargo" ends with a vowel, making it an open syllable. "Iodine" and "radio" both also end in vowels, which categorizes them as open syllables. Hence, this choice does not showcase any closed syllables.
Conclusion
The correct option, "complex disconnect hatch," consists solely of closed syllables, where each word ends in a consonant, creating short vowel sounds. In contrast, the other options contain words that either end in vowels or do not fit the closed syllable definition, illustrating the unique property of the correct choice. Understanding syllable types is essential for mastering phonetics and improving reading skills.
