A reptile is an ectotherm or in common terms, cold blooded. Their body temperature changes with the changes to their environment. So with that in mind, let's look at the available choices.
changes.
* This looks like the correct answer. Notice it doesn't say increase or decrease. But then the question itself didn't specify in what direction the temperature was changing.
stays the same.
* This is in direct contradiction to what a cold blooded animal is. So it's wrong.
always increases.
* This would be quite a trick. If it were true, you'd see a lot of reptiles spontaneously bursting into fire since the temperature during the day constantly changes and this would imply the reptiles getting hotter and hotter and hotter ... until they either die from getting too hot or burst into flame. This isn't happening, so this is definitely the wrong answer.
always decreases.
* Another neat trick. I don't see a whole lot of reptiles encased in ice during the summer which is exactly what this would imply if it were true. Although if it were true, it would be wonderful to power freezers and refrigerators by simply stuffing some poor reptile into the box. Would definitely save a lot of money on air conditioning as well. But it's not and this answer is wrong as well.</span>
