school / Welcome/ our / to

Here's the analysis: * 'school' stressed at first syllable: The word 'school' has one syllable, so the stress is on that single syllable. * 'Welcome' stressed at first syllable: This implies that the word 'Welcome' has two syllables (Wel-come), and the stress is on the first syllable. * 'our' stressed at first syllable: The word 'our' has one syllable, so the stress is on that single syllable. * 'to' stressed at first syllable: The word 'to' has one syllable, so the stress is on that single syllable. Analyze: All the words have stress on the first syllable, but some words have only one syllable, while 'Welcome' has two syllables. However, the stress pattern is not the focus of the difference here, but the syllable count might be the key. Answer: None, since the question isn't provided
