He remained silent until Holmes had, with the help of the audience, identified the correct answer as £6.31.
Also, the exam is composed of 100 multiple choice questions--this means you need to identify the correct answer (by whatever means you can) as quickly as possible.
In a 2014 BBC Wales poll only 48% identified the correct answer.
In case a query molecule is contained in the database (spectral library) to search in, we can use any method of spectral comparison, such as peak counting or dot product, to identify the correct answer.
For example, students may use on-demand hints to retrieve the correct answer without understanding the reasoning behind their response (Aleven and Koedinger 2000), engage in systematic guessing to identify the correct answer (Baker et al. 2004), or simply ignore available help altogether (Aleven et al. 2003).
Furthermore, as a user needs to specify the time of the events in case of physical activity and battery charging related questions, we expected these types of open-ended questions to be relatively harder compared to multiple choice application usage and music questions where users only need to identify the correct answer(s) from a given list.
However, students approach them using various test-taking skills to identify the correct answer.
In the control community, 72% (319/446) identified the correct answer at follow-up and 59% (263/446) did so at baseline.
Each participant is asked to identify the correct answer and then state how sure he or she is that he or she answered correctly.
Finally, on some items, students were more confident about their reasons than their answers, indicating that they were familiar with the underlying scientific principle but unclear on how to apply it to identify the correct answer.
In contrast, if one knows response alternatives will be presented in MCQ format one might feel confident in one's capacity to answer not only by the ability to generate a plausible response, but also by a feeling of knowing leading to anticipation that one could identify the correct answer if given alternatives from which to choose.
