The correct answer is C. week is.
The reason why this is incorrect is because there has to be a comma between the words week and is. The clause 'who is visiting the US this week' is an appositive clause, which means that it has to be set off from the rest of the sentence using commas. Hope this helps!
The correct answer is A. Earth
Explanation:
A root word is a word by itself which can be combined with suffixes and prefixes to create new words, thus root words cannot be shortened but by adding other words or letter before or after them new words are created by mixing the meaning of the root word and the word, syllable or letter added. The words geology, georgic and geode have a common root word which is geo and which is combined with different suffixes such as -logy, -ergic and -de to create new words. The root word geo derives from Greek and means earth, ground or land, as mentioned before the root word is combined with suffixes to create new meanings in this way -logy means the science or study of something which means geology is the study of earth or land; -ergic means produce by, which means georgic is a poem produced or inspired by land (agriculture ) and the suffix -ede means separation which is links to geode definition which is a formation of rocks. Thus, the root word geology, georgic, and geode share is "geo" which means Earth.
