At least when this sentence is read in its most literal sense, it seems that Lawrence is trying to guess or calculate the time it will take for him to complete the job. This interpretation is helped by the fact that the second sentence says that it will help him to figure out his schedule. When we try to make an educated or intelligent guess about something—for example, time or costs—we "estimate" that thing. That is what Lawrence is doing in this sentence.

The sentence merely states that Nigel liked talking for a long time with his friends. Therefore, do not read too much into the sentence. It does not tell us that he liked arguing with them or even that he liked to debate them. The best option is the simplest in this case—"conversation."

Notice in the second sentence that it is admitted that some older people are afraid of new technology. The implication here, however, is that it is unfair to think that this applies in general to all older people. Instead, many use technology with enjoyment and skill. A stereotype is a kind of unfair idea that may be true in some limited way but is not absolutely true. 

The second half of this sentence provides a justification for John's action. From good motives, he took the money from his brother. It seems that everyone overlooked this fact and was judging him negatively. Now, likely everyone was treating him like an outcast or as a criminal. The best option will be one that describes the fact that John had taken the money. Thus, it would seem best to say that everyone treated him as thief. Try to keep your words as close as possible to the context when answering questions like this. You will not always have to do this, but in questions like this one, it makes all the difference!

For this sentence, you are lucky to have Egbert's motto. He didn't want to do anything extra, so he wanted to do a minimal amount of work. The word "minimum" can be used as an adjective to mean "the least". Thus, Egbert wants to do "just enough" to get by with a passing grade.

From the description, the house in question seems to be very elegant and also very simple. We cannot say that it is in poor condition ("decrepit"). All that the sentence tells us is that it does not have much ornamentation; therefore, it is plain and "simple." Something "simple" can still be very elegant, as long as it has an overall good style. This appears to be the case for the house discussed in this sentence.

Notice the description in the second sentence. It is said that one person may love while the other person does not love. This means that the two people do not share in the same love. When something is "mutual," multiple people experience the same thing. When love is just "one way", then we do not have such mutual feelings.

The first (and clearest) clue to this question is found in the clause at the end of the sentence. Clearly, John's body is shaking from fear. This shaking is accompanied by chattering teeth as well. Such fearful shaking is not wiggling. Trembling is a kind of shaking that happens because of fear. Hence, the mention of fear at the start of the question can help you select the correct answer.

To properly complete this sentence, choose a completion that would be a reason to drive slowly out of a driveway. Meeting her brother for lunch downtown and buying a new laptop today are not relevant answers. Sandra would not drive slowly to “hit the mailbox on the way out” or “ignore other cars around her,” so the correct answer is that she would “look both ways on the street”.
