13. I can provide a blessing, a curse, or clarity. I am always running, but I am stuck in a loop. And though I will rule you for most of your life, you will always look up to me. What am I?

Answer: "A Clock" - Reasoning: Seeing the time on a clock can bring you relief, (e.g. your work shift nearly being over), a curse, (e.g. how long you still have left of a work shift), or simple clarification of what time it is. A clock is always running but always returns to where it began, to repeat. Thus, it is stuck in a loop. And as punching at work, appointments, taking to children to daycare, watching a film at the cinema, et cetera, all require you to be at a place at a certain time, time, which you read on a clock, does rule your life. The only exception is when you do not have a schedule to keep. And traditionally, clocks are usually placed on a wall, above eye level, so many people can look at it to see the time

19. A light aloft alone in shadow, I light the way for paths you follow. What am I?

20. Where once there were many, now there are none. Time has done ticking; the hours are done. For now is an end, but also beginning, For darkest is now, but soon shall be thinning. What is it?

Answer: "Midnight" - Reasoning: The riddle is all about following something through to the end - a day. Once the day reaches its end, at midnight, when all the hours of the day are gone, right down to the last second, the clock resets.

22. In this place, people lie, people cry, and people ask why. In this place, people sleep, people weep, and people's solitude, they keep. What is it?

Answer: "Graveyard" or "Cemetery" - Reasoning: Both "people lie" and "people sleep" are indications of many people using this place to lie down, or to sleep, which in itself is an odd thought. Crying and weeping indicate that this is a sad place, and the continued use of "people" allows this to mean not just those who are lying down or sleeping, but those who come to visit them there, (i.e. mourners). People come to ask the person grave why they did what they did that resulted in their death, as a form of mourning, or to ask their chosen God or Gods why they took that person to their grave. And peoples solitude refers to people sleeping on their own, or the mourners usually coming the mourn privately.

27. Endlessly, I hunger, Lazily, I sleep. Murderous, I thunder, Desires, I do seek. Hoarding countless treasures, so my stature I retain, Envious of others whose feet on Earth remain. What am I?

Answer: "The Seven Deadly Sins" - Reasoning: Each sentence structure portrays one of the seven deadly sins from Christian theology, with the exception of the final 5 words. In order according to the riddle, these are; gluttony, sloth, wrath, lust, greed, pride and envy. The final 5 words, "whose feet on Earth remain", act in conjunction with the section on envy, demonstrating the perspective of a sinner in hell, who is envious of those still alive, and thus can still repent for their sins in order to enter Heaven.

28. Whiling away the hours of flowers, Walking through fields of gold. Preening and pruning in lights fading hours, For petals to freeze in the cold. What is it?

Answer: "The Four Seasons" - Reasoning: This riddle takes the perspective of plant life during these times of the year, where each line represents one of the four seasons of the year; Spring, Summer, Autumn and Winter. Spring - where flowers are blooming - Summer - where fields of farm crop mature and turn golden in colour, before being harvested - Autumn - where the tree's shed their leaves and days grow shorter - and Winter - where the cold leaves frost and freezes plants.

29. I am known everywhere as a criminal, yet I have never done anything illegal. I always have an inside angle on you, and there are two of me for every one of you. What am I?

Answer: I am... the crook of an elbow! The crook is called a crook (obviously), and as your arms are on the side of your body, the insides of your elbows most nearly always have an inside angle on you; it's not psychological at all! And for every arm is an elbow, so two elbows means two crooks of an elbow per person.
