Hi Guyz!
Iam taking part in a online quiz competition and found some answers with google.For some questions though ,googling didnt help much.Tried searchin for images ,but couldnt crack it.
So,thought you guys could help me out. ;-)
Thanks.
1.Whats the connection between these two pictures.
2.Identify this brand of gun more famous in another context.
3.RElated to the world of automobiles.What is this lady's claim to fame.
4. This spider is named for the unique marking on its rear segment which is shown in the picture. So, who is it named after? (Cryptic clue- Think of a nice sobriquet for Thomas Alva Edison's mom, though they may be more than one.)
