Sometimes the built-in question types are not good enough to create a complex question. In this case your best option is to use the Embedded answers (Close) questions. 
​Embedded answers (Cloze) questions consist of a passage of text (in Moodle format) that has various answers embedded within it, including multiple choice, short answers and numerical answers.
The size of INPUT HTML ELEMENT ( Short and Numerical) will be adjustable to the length of the longest answer (good or bad) + a random number (0 to 15% total length).
In this case the size  of the input box can help your students to find the right answer easier.  See the image below:

I've tried to install "Moodle" to a free web hosting sever and my proper website as well so many times, but I wasn't successful at all. Sometimes I had problem with PHP  settings (safe mode), sometimes with "moodledata" folder (can't create it or wasn't safe enough for the installer) and even if I used ssl connection to upload every files, it took ages. 
But finally I find a really nice and easy solution. You don't need to create any database and you don't need to upload anything. Just few clicks and you've got a proper Moodle site.
I hope you find it useful.
