I played the game in that website, mostly I lost lolz, so I use copy and paste for those words I could not make the right choice to here.
1) The suspect in the thwarted bombing last month flew from Ghana to Nigeria to the Netherlands, boarding the flight to Detroit at Schiphol Airport, outside Amsterdam.
In this sentence, suspect means: someone is under suspicion.
A suspect is a person who is believed to be guilty of a crime. If you leave the scene of a murder with blood on your hands and a weapon in your pocket, you’re likely to become a prime suspect.
If others believe you have committed a crime, you are a suspect. The word can also be used as a verb and an adjective. To suspect someone of something is to believe that they probably did it. Do you ever suspect your parents of taking some of your Halloween candy? If something such as someone's excuse or motive is suspect, it seems a bit off. That bad-smelling piece of fish is suspect — you'd better not eat it.
2) Recall means reminiscence.
Recall is a noun that means the process of remembering (especially the process of recovering information by mental effort)
3) Perennial means recurring again and again
Perennial typically describes things that are permanent, constant, or repeated. If you fight with your parents every year over whether they really must invite your annoying cousins for Thanksgiving, you could call that a perennial conflict.
Perennial typically describes things that are permanent, constant, or repeated: a perennial conflict. A perennial plant (also called a perennial) lasts more than two years because it produces flowers and seeds from the same root structure every year. Perennial is from Latin perennis, from the prefix per- "through" plus annus "year." Latin annus is also the source of our English word annual. An annual plant lives only one year or season.
4) Solitude is the state of being alone. You might crave solitude after spending the holidays with your big, loud family — you want nothing more than to get away from everyone for a little while.
Solitude can also refer to a place where you're completely alone. The middle of the woods, the top of a big mountain, the middle of a vast desert, even your room — these are places where you might go for solitude. Solitude comes from the Latin word solitudinem, which means "loneliness," but if you have moments of solitude that doesn't necessarily mean you're lonely. The word solitude carries the sense that you're enjoying being alone by choice.
5) Factual means real (facts, fact, some facts but will be used differently in a sentence with fact)
If something is factual, it can be proven, like your mother's story about the bear that is factual because she took a picture of it standing next to the family car.
Something factual is real. It is based in fact, meaning it can be proven, repeated or observed. In fact, fact is the root of the word factual, from the Latin word factum, meaning "event, occurrence." The factual part of a story is the part that really happened — the rests gets more outlandish and make-up every time someone tells it. Evidence makes something factual.
