No. This isn't a section for doing the homework for you. You need to attempt it, and then maybe we'll give you some hints and advice on where to get going.

look at the words for ages.

 

see if you really know what each word means.....

 

usually if you really understand the words you already have the answer.

 

then think if you have ever seen any similar type of question or words.

 

compare those to your presesnt question.

 

if you come up empty ..research the words using google.

 

good luck.
