Duration / Feedback / Feedback Duration

Greetings,

The study is about English grammar and the treatment consists of 99 fill-in-the-blank sentences. Half of the sentences are untimed, i.e. participants move at their own pace but the other half are timed meaning that each sentence is shown for 27 seconds and it automatically moves to the next sentence which is untimed. All the sentences must show feedback but feedback for the timed sentences must be displayed for 3 seconds before moving automatically to the next sentence which is untimed.

Here are my questions below:

1. How do I underline text stimuli? The stimuli are underlined "stimuli bank" but it doesn't show up in the preview.
   
2. How do I display some individual sentences for exactly 27 seconds as well as the feedback for each of these timed sentences? In other words, sentence1 is shown for 27 seconds followed automatically by the feedback for 3 seconds before it moves on automatically to sentence2, along with its feedback, which are not timed.
   
3. I need to use fill-in-the-blank responses but how do I display "correct" and "incorrect, the correct answer is..." feedback for each sentence? How would I go about displaying the feedback for some of the sentences for exactly 3 seconds before it automatically moves on to the next sentence?
   
4. How do I upload several images all at once? 
   
5. How do I place three sentences on their on their individual line instead of having them follow each other like sentences in a paragraph? I know how to create paragraphs but I just some sentences to be next to each other on their own line. 
   
6. I have two experimental groups and one control group. Do I need to create three separate experiments?
