The boxed words are a compound subject.
In a sentence talking about people, the people are subjects of that sentence. Subjects are basically what is being talked about.
Because there are two people being talked about, Bob and Al, the subjects are counted as one, or compounded. This just means that you read the sentence as [Bob and Al] instead of [Bob] and Al.
Compound verbs follow the same concept, but for action words. For example, “to sing and to dance”. However, in this case since the boxed words are subjects, they are a compound subject.
This question is incomplete. Here's the complete question.
Read "Seals with high-tech hats are collecting climate
data in the Antarctic," by Katherine J. Wu.
Choose a problem (and solutions) described in the text. Explain what the problem is and why it matters, using
examples, facts, and details from the text. If possible, describe any solutions proposed in the text.
Answer:
The problem was that, because of the low temperatures, collecting data beneath the surface of the Southern Ocean was not possible with the current instruments.
Explanation:
The solution found was to set specialized sensors in elephant seals´heads to trace the variations in temperature while they swim the Antarctic waters.
The findings of this research are important because they should be included in the present climate model, to better understand how climate change is altering the way Antarctic waters, and the entire world´s water, move.
Margaret’s message to John II in her letter of 28 October 1470 was how was she going in the country, that she had sold some 'dysshes, plateres, and sawceres' and that she send the money to him. She advised him to take into account how he spent the money. She encouraged him to be brave. She said that she thanked God for how God guided his way, but that he must take care. And she finished her letter with the following phrase:
'God make here a good wooman' (hoping that God helped her and made of her a good person)
