The correct answer is B. <span>They are terribly thirsty.
They were working as guardians of a bean field. One day, there came a monkey which they chase to avoid eating the beans. Unfortunately, a time came when they got extremely thirsty so they had no other choice but to leave the field and drank in a pond in the forest.</span>
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!

Let's imagine someone working in business - they could for example work in an office, in front of computer, analysing the finances of their company. They would not necessarily be talking to the clients directly or presenting the company to the public - so the correct answer is "a good public speaking voice"</span>
