[EX Q]: Article: Do you want to write your password down so that no one can see it, or do you want to send someone a secret message? Knowing how to make an invisible ink message will have you feeling like a secret agent in no time. These are instructions for making invisible ink using baking soda. Difficulty: Easy Time required: A few minutes  What you need: Baking soda, Paper, Water, Light bulb, Paintbrush, Measuring cup, Purple grape juice Here's how: There are at least two methods of using baking soda as invisible ink. Mix equal amounts of water and baking soda. Use a paintbrush to write a message onto white paper, using the baking soda solution   as "ink". Allow the ink to dry. One way to read the message is to hold the paper up to a heat source, such as a light bulb. The baking soda will cause the writing in the paper to turn brown. The second way to read the message is to paint over the paper with purple grape juice. The message will appear in a different color1. Tips: If you are using the heating method, avoid burning the paper. Baking soda and grape juice react in an acid-base   reaction, producing a color1 change in the paper. Grape juice concentrate   results in a more visible color1 change than regular grape juice.

[EX Q]: Article: (Reuters)The Thunderbird is one of the most readily recognized creatures of American Indian mythology.While the vast majority of biologists believe the Thunderbird myth to be nothing more than a spiritual symbol, some zoologists believe that the hard may actually exist.    I still vividly recall seeing an impossibly large raptor when I was five years old, which a few people have said might be the Thunderbird.Standing in my grandmother's back yard in Alabama, I recall watching an enormous black bird with a swallow - like tail flying directly over me from an oak tree. Its wingspan seemed to be at least three times my height, which would have made it at least fourteen feet across. While the early childhood memory is often unreliable, I clearly remember the details of the  "Thunderbird".To this very day, I sometimes stand on my grandmother' s yard, eyeballing the old oak tree, but I have not yet seen another bird that resembles the giant bird.I have seen eagles, and hawks - but never another Thunderbird. Other modern sightings of what may have been thunderbirds have also occurred.In 1977, three boys were playing in a neighborhood in Illinois.They reported that two large birds chased after  them.One of the boys was attacked and suffered somewhat serious injuries, He was carried a few  feet off the ground, before the bird dropped him and disappeared into the wilderness. Several people interviewed the boys and their story remained the same, even under the pressure.the description of the birds somewhat matched the Andean condor ; however, these  massive condors have never been known to exist in the United States. Another sighting came in 2002, in Alaska, when many people reported seeing a bird with a fourteen - foot wingspan.After being investigated, it was finally concluded that the bird was most likely a particularly large sea eagle, which typically has a wingspan of six to eight fickle. I will probably never know what the strange -looking giant bird from the oak tree was, and biologists will probably never be able to fully confirm the identity of the giant raptors spotted in Illinois and Alaska.If the Thunderbird does indeed exist, it will probably continue to remain mysterious. 
 Question: What's the best title for the passage? 
 Options: (A) A massive bird spotted in America (B) Could the thunderbird actually exist? (C) Some strange birds sighed by people (D) Sea eagle, condor, raptor or thunderbird?
