【题目】根据短文理解，选择正确答案。
There are 115 distinct (独特的) species of pine trees with 35 native to North America. Pines are defined as evergreens with long, needle-like leaves and are only native to the northern hemisphere. Pine trees are an adaptable and tough species that can survive in many conditions where other plants cannot. The average pine tree is 45 to 60 feet tall, but some are nearly twice as high.
Western White Pine
The western white pine grows the tallest of any pine tree, reaching up to 110 feet in height. They have blue-green needles arranged in bundles (束) of five and produce a long cone (球果).

The bristlecone pine grows slowly, reaching about 20 feet tall. It is one of the oldest species of pine.
Mexican Pine
The Mexican pine can grow to 50 feet tall, with long, slender needles that drape (下垂) off it like a weeping willow (柳树). Often nicknamed the “willow pine”, it is native to Mexico. Its leaves can droop up to 12 inches long.
Sugar Pine
The sugar pine is another of the large pine species, such as the bull pine, but it also has the largest cones of any pine species, at 10 to 20 inches long. It grows from Oregon to California and is often used for construction.
