Answer:  C. A species is brought to a new environment where it has no predators.
Explanation:
According to the <em>Green Invaders</em> article, invasive species are plant species that people brought with them when they moved to the United States because they wanted to make the vegetation more aesthetically pleasing. 
The article mentioned how this could be bad for the ecosystem however because most insects are plant specific which means that they only feed on certain plants and without those plants, they could die off. 
The insects are the predators for plants therefore and if they are unable to eat these new invasive plant species then that means that these plant species are now in an environment where they have no predators. 
 
        
             
        
        
        
Answer:
Option D, The end of the great Texas cattle drives, is the right answer.
Explanation:
 The Spanish settlers were the first to bring the longhorn cattle in North America. During the course of time, Texas became home to millions of longhorn cattle. The cattle ranchers of the area wanted to sell them in the markets of East and North for the reason the demand was high and the supply was low. Such cattle drives came to an end in the decade of 1880s for various reasons. The invention of barbed wire, the expansion of railroads and too many cattle grazed on the crowded ranges and thus there was not enough grass to feed them all, were some of the significant reasons.
