[TYPO3] No captcha for pbsurvey? How to wrap pbsurvey questions?

[Bing Du]

Hi,

Typo3 V4.0.4
Questionaire (pbsurvey) 1.0.8
freeCap CAPTCHA (sr_freecap) 0.4.4

In the pbsurvey Access configuration, 'Show Captcha before entering
survey' is enabled.  But I don't see any captcha show on the survey page? 
What did I miss?

Another question, no matter how long is the question, pbsurvey shows the
question in one line.  It doesn't fit in our narrow layout.  Can long
questions show up in multiple lines?  How?

Thanks in advance for any help,

Bing
