Days per Winter That Lakes Have Surface Ice

Lake	Latitude (degrees)	1980–81	1985–86	1990–91	1995–96	2000–01	2005–06
Spirit Lake	43.46	102	135	121	134	147	126
Lake Kegonsa	42.97	94	116	104	113	124	101
Näckten	62.913	177	168	144	174	133	134

It is common for freshwater lakes near or above a latitude of

4 5^{\circ}

north of the equator, like Lake Stechlin in Germany, to accumulate surface ice in winter. A study from 1980 to 2006 showed that, in general, the number of days per winter that such lakes have measurable amounts of surface ice is declining. However, a researcher claimed that some lakes have instead seen an increase in the duration of ice.

Which choice best describes data in the table that support the researcher’s claim?

Spirit Lake had fewer days of ice in the winter of 1980-81 than it did in the winter of 2005-06.

Näckten had more days of ice in the winter of 1980-81 than it did in the winter of 2005-06.

Näckten is at a higher latitude than Lake Kegonsa and typically had fewer days of ice per winter than Lake Kegonsa did.

Näckten is at a higher latitude than Lake Kegonsa and typically had more days of ice per winter than Lake Kegonsa did.
