I’m a bit confused on your question, I’m not sure which of the followings you are referring to
Answer:
la causa principal es la quema de combustibles fósiles
<h2>Correct answer:</h2><h3>Laura tiene tantos vestidos como Paula.</h3>
Here we use <em>comparison of equality, </em>so this just as Tan...como conveys the idea of as … as. This is used when referring that two nouns are equal to one another. To compare two nouns using another noun, we use the formula:
<em>tanto + noun + como </em>
So vestidos is a masculine plural noun. Finally, this sentence means:
<em>Laura has as many dresses as Paula.</em>
