Article: On 10 May 1963, John XXIII received the Balzan Prize in private at the Vatican but deflected achievements of himself to the five popes of his lifetime, Pope Leo XIII to Pius XII. On 11 May, the Italian President Antonio Segni officially awarded Pope John XXIII with the Balzan Prize for his engagement for peace. While in the car en route to the official ceremony, he suffered great stomach pains but insisted on meeting with Segni to receive the award in the Quirinal Palace, refusing to do so within the Vatican. He stated that it would have been an insult to honour a pontiff on the remains of the crucified Saint Peter. It was the pope's last public appearance.

Question: Who officially awarded the pope the Balzan Prize?

Article: A commutated DC motor has a set of rotating windings wound on an armature mounted on a rotating shaft. The shaft also carries the commutator, a long-lasting rotary electrical switch that periodically reverses the flow of current in the rotor windings as the shaft rotates. Thus, every brushed DC motor has AC flowing through its rotating windings. Current flows through one or more pairs of brushes that bear on the commutator; the brushes connect an external source of electric power to the rotating armature.

Question: What does the communicator do?
Ans: reverses the flow of current in the rotor windings


Article: Using histological stains on expectorated samples from phlegm (also called "sputum"), scientists can identify MTB under a microscope. Since MTB retains certain stains even after being treated with acidic solution, it is classified as an acid-fast bacillus. The most common acid-fast staining techniques are the Ziehl–Neelsen stain and the Kinyoun stain, which dye acid-fast bacilli a bright red that stands out against a blue background. Auramine-rhodamine staining and fluorescence microscopy are also used.

Question: What's another word for "sputum"?
Ans:
phlegm
