powerhouse turns

[katochan pe]

I'd be most grateful, if you could answer my questions regarding two sentences below:
a) With powerhouse turns in critically acclaimed films such as The Heat and A History of Peace,
audiences are well acquainted with Bella's on-screen tenacity.
>> What does 'powerhouse turns' mean in this case?
b) She gives a voice to the voiceless through her work with the Haitian organization Femmes En Democratie
a chapter of Vital Voices Global Partnership, whose mission is to expand the roles of Haitian women
in generating economic opportunities, increasing political participation and protecting human rights.
>> What does 'give a voice to the voiceless' in this sentence?
Thanks in advance.

a) With powerhouse turns in critically acclaimed films such as The Heat and A History of Peace,
audiences are well acquainted with Bella's on-screen tenacity.
>> What does 'powerhouse turns' mean in this case?

The dictionary defines "turn" as "brief theatrical act or stage appearance"
turns
So, it must mean that this actress played roles that were minor but powerful and captivating to the viewers.

]b) She gives a voice to the voiceless through her work with the Haitian organization Femmes En Democratie
a chapter of Vital Voices Global Partnership, whose mission is to expand the roles of Haitian women
in generating economic opportunities, increasing political participation and protecting human rights.
>> What does 'give a voice to the voiceless' in this sentence?

The voiceless points to Haitian women in this case, who are poor and weak in the world and cannot be heard about in the media.
By speaking in their behalf through her participation in the organization, this person became "the voice" for these women.

Just my two yen.

My two yen are that I agree completely with epigene! I never knew that definition of turn had its own entry in the dictionary, though!
