The phrase "more occasioned" can be replaced with a variety of synonyms to add more depth and variety to your writing. Some alternatives to consider include "further provoked," "increased the likelihood," "spurred on," "elicited," "instigated," and "catalyzed." Each of these synonyms conveys a slightly different shade of meaning, from suggesting that an event would not have happened without this triggering factor to implying that the situation would have occurred eventually, but this occurrence hastened or intensified it. Experimenting with these and other synonyms can make your writing more precise and interesting, so do not be afraid to play with language.
