Q: (CNN) -- A federal grand jury Thursday charged two friends of Boston Marathon bombing suspect Dzhokhar Tsarnaev with obstructing justice and conspiracy to obstruct justice, the U.S. attorney's office in Boston said.

Azamat Tazhayakov and Dias Kadyrbayev -- 19-year-old roommates and Kazakh nationals who began attending the University of Massachusetts-Dartmouth the same semester as Tsarnaev -- were charged in May with conspiracy.

It is not clear whether Thursday's indictment represents a second conspiracy charge.

Thursday's indictment accuses Tazhayakov and Kadyrbayev of helping Tsarnaev after the April 15 bombing by taking items from his dorm room to keep them from investigators.

If convicted, Tazhayakov and Kadyrbayev could be sentenced to a maximum 20 years in prison on the obstruction count and up to five years on the conspiracy count, the U.S. attorney's office said. They also could be fined $250,000.

Arkady Bukh, Tazhayakov's attorney, said his client is not discouraged. He also said that Tazhayakov did not touch any of Tsarnaev's items.

"He feels very strongly he'll be able to be able to convince a jury that's he's innocent," Bukh said. "There's no evidence of intent, no incentive to help (Dzhokhar), no motive to destroy anything."

The three students socialized and texted each other, the indictment says.

On April 18, three days before the FBI searched Tsarnaev's dorm room, Tazhayakov and Kadyrbayev allegedly went into the dorm, took Tsarnaev's laptop and a backpack containing Vaseline, a thumb drive, fireworks and a "homework assignment sheet" and took them back to their New Bedford apartment, the indictment states.

Answer the questions at the end based on the text.

(CNN) -- Charles Dickens, who was born 200 years ago this week, created some of the best-known and most loved figures in English literature, from Oliver Twist and David Copperfield to Pip, Miss Havisham and Magwitch.

But of all the characters he wrote about, none played as important a role in his work as that of London itself: its hustle and bustle, its glittering promise and grimy streets and the extremes of poverty and wealth experienced by those who lived there.

Alex Werner, the curator of the Museum of London's "Dickens and London" exhibition, says the city was "absolutely central" to Dickens' work.

"It triggered his imagination," he told CNN. "He called it his 'magic lantern', and would spend hours pacing the streets, drawing inspiration from what he saw around him."

London was Dickens' muse, helping to spark his creativity and provide ideas for some of the most memorable characters, settings and plot twists in English literature.

As Britain -- and literature lovers the world over -- celebrates Dickens' bicentenary in 2012, what better time to explore the city he knew and loved best?

Dickens in London

Dickens moved to London as a child, but the family soon ran into financial trouble: His father was sent to debtors' prison, and at the age of just 12, Dickens was forced to work in a shoe polish factory -- Warren's Blacking Warehouse, at Hungerford Stairs -- to support his mother and siblings.

"It was a crazy, tumbledown old house, abutting of course on the river, and literally overrun with rats... the dirt and decay of the place rise up visibly before me, as if I were there again," he later told his biographer, John Forster. Both the warehouse and the stairs, near what is now Embankment tube station, are long gone.
