Input: Consider Input: In the meantime the Indians had retreated to the lava beds and bade defiance to the soldiers. General Wheaton, commanding the district of the Lakes, ordered the concentration of troops from Camps Warner and Bidwell, while General Canby sent the forces under Colonel John Green and Major Mason from Ft. Vancouver to join the command under General Wheaton. As soon as the settlers could fort up for mutual protection, the entire forces of regulars and volunteers were concentrated at Van Bremer's ranch west of the lava beds under General Wheaton and at Land's ranch on the east side of Tule Lake and directly north of the stronghold. Such was the disposition of the forces when I arrived at headquarters at Van Bremer's ranch. By orders of Governor Grover of Oregon the volunteers under Captains O. C. Applegate and Kelley were placed under the command of General Wheaton. The two companies numbered about 225 men, and were commanded by General John E. Ross, a veteran Indian fighter, but too old to withstand the hardships of a winter campaign against Indians. The men were all poorly provided with clothing and bedding, most all having taken only what they could strap behind their saddles, but in spite of this and a temperature often below zero, no murmur was heard, and all anxiously, eagerly looked forward to a meeting with the brutal savage murderers of their fellow citizens. Such were the conditions when I arrived at headquarters. <sep>The area to where the Indians had retreated, where in proximity to Van Bremer's ranch?<sep>Yes, because the lava beds stronghold was east of Van Bremer's ranch

Output: Yes


Input: Consider Input: Rock layers extend laterally, or out to the sides. They may cover very large areas. This is especially true if they formed at the bottom of ancient seas. Seas are very large areas of water. Over time, sediment builds up on the seabed. They will be covered with the same types of material. As rocks form out of this sediment it will all be the same type. The rocks may be forced up above the water as Earths plates move. Rivers may eventually run across this area. The river will cut into the rock and erode it away. The layers of exposed rock on either side of the river will still match up. Look at the Grand Canyon in Figure 2.27. Its a good example of lateral continuity. You can clearly see the same rock layers on opposite sides of the canyon. The matching rock layers were deposited at the same time. They are the same age. <sep>What is the Grand Canyon a good example of?<sep>lateral continuity

Output: Yes
