Answer:
The only word in this sentence that contains a long vowel is the word "like."
Step-by-step explanation:
A long vowel is pronounced the same way has the letter itself. Let's break apart each of the words.
dog- Here, the vowel "o" makes an "ah" sound. It is not a long vowel because the "o" does not make an "oh" sound.
like- The vowel "i" makes an "ay" sound. This is the same as the pronunciation of the letter "i." Therefore, the "i" is a long vowel.
tennis- This word has two vowels - e and i. The "e" is prounounced like "eh" and the "i" is prounced like "ih." They are short vowels.
balls- The vowel "a" is prounounced like "ah." It is also a short vowel.
