From this list of roots, choose good descriptions for the plants and animals you are naming. a silly bird that runs around in circles (select 3 words.) solus (alone) curso (to run to and fro) fervo (to glow or burn) magnus (large) avis (bird) clarus (loud) mare (sea) flos (flower) canto (to sing) rotundus (circular) celer (swift) penna (feather) aqua (water) herba (grass) brevis (small)

The words I would choose are avis, curso, and rotundus.

Explanation:

The reason for that choice is simple. We need to describe a bird (avis) that runs around (curso) in circles (rotundus). Those are the best options among the one in the list.

The use of Greek or Latin names for fauna and flora was systematized by Carl Linneaus in the 18th century. Linneaus was a Swedish naturalist who created a hierarchical systems of grouping animals and plants. The names are, however, constituted of two parts - in this question, we were asked to choose three words -, being called binomial nomenclature (two-name naming system). The names usually indicate what animal species that is plus a characteristic is possesses. For instance, the Asian tiger mosquito is called Aedes albopictus - aedes means mosquito, albopictus means painted white. As we can see, the word albopictus is an agglutination of two words (albo for white, pictus for painting). We could, thus, do the same to name our bird. So, the silly bird that runs around in circles could be called Avis cursorotundus.

I don't see any italics in the question, but:

In A, there should be commas after each item. In the U.S. the commas would be inside the quotes: Is the word "their," or the word "there," correct in that sentence? I've read that in some other areas the convention is to put the commas outside the quotes: Is the word "their", or the word "there", correct in that sentence? but I'm not familiar with that.

In B, the word "love" should be quoted as it appears in this sentence.

In C, I think (I'm skilled, but not an certified grammarian) the "T" should be quoted, like so: I often forget to cross my "T"s when I'm writing quickly.

D is, I believe, correct. Again, this is by U.S. conventions. Elsewhere (England, at least) I think it would be written as: Mike's home address begins with a "2".
