hey there,
your answer is a) today we hope for clear skies.
let's look at the word(s) progressive verb. progressive means its happening right now. it is not going to happen and it has not already happened. it is happening right now. the sentence "today we hope" in option a is an example of a progressing verb. they are hoping right now. options b, c and d are not progressing verbs. they contain the words have, roared and will be. those words tell us that it has either happened or will happen. a is your answer.
best of luck,
