1. The correct answer is D. Eurydice.
Eurydice was Orfeo's love who unfortunately died so he went after her to Hades to bring her back from the dead. The only ultimatum he had was not to look at her while they were still in Hades, until they resurfaced. However, he succumbed to his desire to have a look at her and thus she remained dead forever.

2. Basso continuo is a form of music which literally translates as 'continuous bass.' The instruments widely used to perform this type of music were keyboard instruments, cellos and a bassoon. So based on your options, I would pick D. organ and cello, because violins, flutes, and timpanis are not used here.

3. Although I'm not entirely sure, I would pick A. arias. Arias are musical pieces within operas sung by one single voice and resembling an actual song. Recitatives are not really sung as told using normal voice; orchestras and choruses I believe involve more than one person, so they would be incorrect.

4. I think the correct answer is C. sonata, although I'm not sure about this answer either. Although it can be performed by one instrument, it is also often performed accompanied by another instrument. There are several movements in each sonata, which is why I believe that is the correct answer.

5. I would say these are examples of music for D. keyboard instruments. First of all, they are musical pieces created for instruments, so we can rule out church choirs and solo vocalists immediately. Additionally, toccatas are written for keyboard instruments, not for other instruments, so that is why I ruled out orchestras as well. 

No question so i cant answer
