Q: In this task, you will be shown an extract from a movie plot. You need to read the extract and create questions that can be answered from the extract. The questions should be well-formed and grammatically correct. The questions should be completely answerable from the given passage and should not require any external knowledge. Subjective questions are not allowed. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is factoid or not is to see if two different people with average reading/comprehension skills would come up with the same answer after reading the passage.
Sister Rachel Taylor (Erin Chambers) of Boise, Idaho is an eager young missionary of the LDS Church who has been sent on an 18-month-long mission to Austria. Rachel finds herself having a hard time adjusting to her new cultural surroundings in the foreign country. Due to differences in opinion, she is also unable to get along with the companion missionary that was assigned to her by the church. Taking a note from the very teachings she is trying to spread, Rachel eventually learns to accept others' differences and get along peacefully with her companions even if they disagree on how to go about conducting the work for which they volunteered.
