Problem: Chicago Cubs:

The team's commitment to contend was complete when Green made a midseason deal on June 15 to shore up the starting rotation due to injuries to Rick Reuschel (55) and Sanderson. The deal brought 1979 NL Rookie of the Year pitcher Rick Sutcliffe from the Cleveland Indians. Joe Carter (who was with the Triple-A Iowa Cubs at the time) and center fielder Mel Hall were sent to Cleveland for Sutcliffe and back-up catcher Ron Hassey (.333 with Cubs in 1984). Sutcliffe (55 with the Indians) immediately joined Sanderson (85 3.14), Eckersley (108 3.03), Steve Trout (137 3.41) and Dick Ruthven (610 5.04) in the starting rotation. Sutcliffe proceeded to go 161 for Cubs and capture the Cy Young Award.

A: due to injuries to Rick Reuschel (55) and Sanderson

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The conventional merit-system degree is currently not as common in open education as it is in campus universities, although some open universities do already offer conventional degrees such as the Open University in the United Kingdom. Presently, many of the major open education sources offer their own form of certificate. Due to the popularity of open education, these new kind of academic certificates are gaining more respect and equal "academic value" to traditional degrees. Many open universities are working to have the ability to offer students standardized testing and traditional degrees and credentials. A culture is beginning to form around distance learning for people who are looking to social connections enjoyed on traditional campuses. For example, students may create study groups, meetups and movements such as UnCollege.
What do most open education sources offer?
A: own form of certificate

Question: The gut is generally an almost straight tube supported by the mesenteries (vertical partitions within segments), and ends with the anus on the underside of the pygidium. However, in members of the tube-dwelling family Siboglinidae the gut is blocked by a swollen lining that houses symbiotic bacteria, which can make up 15% of the worms' total weight. The bacteria convert inorganic matter such as hydrogen sulfide and carbon dioxide from hydrothermal vents, or methane from seeps to organic matter that feeds themselves and their hosts, while the worms extend their palps into the gas flows to absorb the gases needed by the bacteria.

QUES: Like other settled, agrarian societies in history, those in the Indian subcontinent have been attacked by nomadic tribes throughout its long history. In evaluating the impact of Islam on the sub-continent, one must note that the northwestern sub-continent was a frequent target of tribes raiding from Central Asia. In that sense, the Muslim intrusions and later Muslim invasions were not dissimilar to those of the earlier invasions during the 1st millennium. What does however, make the Muslim intrusions and later Muslim invasions different is that unlike the preceding invaders who assimilated into the prevalent social system, the successful Muslim conquerors retained their Islamic identity and created new legal and administrative systems that challenged and usually in many cases superseded the existing systems of social conduct and ethics, even influencing the non-Muslim rivals and common masses to a large extent, though non-Muslim population was left to their own laws and customs. They also introduced new cultural codes that in some ways were very different from the existing cultural codes. This led to the rise of a new Indian culture which was mixed in nature, though different from both the ancient Indian culture and later westernized modern Indian culture. At the same time it must be noted that overwhelming majority of Muslims in India are Indian natives converted to Islam. This factor also played an important role in the synthesis of cultures.

What did the Muslim invaders staunchly keep after invading?
What is the answer?

Islamic identity
