If you are walking along a highway, always walk on the shoulder: None of the answers is correct Facing the traffic flow With the traffic flow Going in any direction you choose

Facing the traffic flow.

Explanation:

While walking along a highway where there are no sidewalks, it is best to walk along the side of the traffic where one is able to see the oncoming traffic. This way, it will enable the person to be conscious of the traffic with both his ears and eyes. He will be able to see and hear the vehicular movement and thus, steer clear of any possibility of accidents, for the traffic is coming towards him.

On the other hand, if a person walks along with the traffic flow, then he will have to rely only on his ears for the traffic and be blind against any oncoming vehicle from behind. This will pose a greater risk for the person walking on the highway.

Thus, it is best to walk on the shoulder facing the traffic flow.

Options:

A. Grasses and ants

B. Ants and grasshoppers

C. Grasshoppers and Texas cottonmouths

D. Texas cottonmouths and red-shouldered hawks

B. Ants and grasshoppers

Explanation:

Looking at the partial Texas food web that is given below in the diagram attached, it shows that the Texas horned lizard feeds mainly on ants and grasshopper as a secondary consumer in the food web. As a result of this, the population of ants and grasshoppers would be often put in check and regulated.

However, if a disease suddenly reduces the population of the Texas horned lizard, it means that ants and grasshoppers won't be heavily preyed on anymore, since the population of their major predator has now been reduced.

Therefore, a reduction in the population of Texas horned lizard would result in the increase in the population of ants and grasshoppers.
