Pick the word that best completes the following sentence. _______ ist es sehr kalt.

“Heute” means “today,” so “Heute ist es sehr kalt” means “Today it is very cold.” “Gestern” means “yesterday” and would normally go with the past tense here, such as “Gestern war es sehr kalt.” “Zwanzig” means “twenty,” and “ohne” means “without,” so neither fits the sentence.
