Wait, "can’t" could be "can't", "cannot", "am unable to". That's three alternatives. Let me adjust.

So the final answer would be all the words converted with three options each, using spintax syntax, with proper nouns skipped. Since there are no proper nouns in the original text, all words are replaced. Let me confirm the proper nouns list to be sure. Proper nouns are names, places, titles, brands. Since the original sentence only has common words, all are replaced. So the modified text is as follows.

Next word is "can’t". That's a contraction of can not. Alternatives could be "Can’t|Able to not|Unlikely to". But "can't" is a contraction. Maybe "Unable to|Not able to|Cannot". But the user said to use three alternatives. So maybe "Cannot|Can't|Am unable to".

Last word is "that". Alternatives for "that" might be "that|this|it". But "that" is a demostrative. Maybe "that|it|this". But need to check if there are other options. Could also use "this|it|that specific one". Wait, but maybe keeping it simple. So "that".
