The present perfect refers to an act that took place in the past, from the perspective of the present. "I have eaten" means that at some point in the past, eating occurred. Now (at the present), it is over.
The simple present tells you about what's going on currently. "I eat" means that the act of eating is ongoing. (Though it can also refer to a habitual act; I may not be eating right at this instant, but it's the sort of thing that I could be doing right now, because the eating isn't complete.)
The definition that best matches the meaning of “lore” given in the dictionary is:
“A body of knowledge or tradition of superstition or a lesson”.
<u>Explanation:</u>
The word lore means knowledge or tradition that is being known or held by a group of people of a particular sect, whereby they pass it on from one generation to the next using word of mouth.
It may be the knowledge of certain traditional herbs used as medicine or some superstitions that may be passed on to keep a check on the behavior of the concerned sect, or it may be some mythological stories that be passed on through generations.
