Problem: Singularity is an experimental operating system (OS) which was built by Microsoft Research between 2003 and 2010. It was designed as a high dependability OS in which the kernel, device drivers, and application software were all written in managed code. Internal security uses type safety instead of hardware memory protection.

Based on the paragraph above can we conclude that "Singularity was designed my Microsoft and was predicted to increase it's revenue by over a billion dollars."?

A: It's impossible to say

Problem: Well, I'm not for photo licensing. Let me say something about Columbine. Listen, we've got gun laws. He says we ought to have gun-free schools. Everybody believes that.

Based on the paragraph above can we conclude that "The speaker does not believe in unequivocal disarmament."?

A: Yes

Problem: Digging in a different trench Phoenix's robotic Arm connected with a hard surface that has scientists excited about the prospect of next uncovering an icy layer. "We have dug a trench and uncovered a hard layer at the same depth as the ice layer in our other trench," said Washington University robotic arm investigator for Phoenix, Ray Arvidson. The arm tried at least three times to penetrate the layer, but was unsuccessful. As a result the arm went into a holding pattern, awaiting its next commands.

Based on the paragraph above can we conclude that "The arm tried at least three times to penetrate Ray Arvidson, but was unsuccessful."?

A:
No
