Mr. X during the recent GCQ went to Tagaytay to visit his friends for 3 days.
Little did he know, the President will revert his announcement from GCQ to
MECQ. Due to lack of transportation, he was forced to walk from Tagaytay to
Fairview. While traversing the secluded area of Aguinaldo Highway, Mr. X got
thirsty hence he opened his can of soda. He got starved so he bought food
from a timely passing taho peddler. He decided to rest for a while, sat on a
huge slab of stone where the back portion is covered with green vines and
vegetations but adjacent to that was a deep ravine. When he decided to lean
his back, he fell and went inside a huge tunnel-like sliding cave with clean
and refreshing water, smooth surface but with dark surroundings and
seemed without ending. After an agonizing 1 hour of continuous sliding,
tumbling, and freewheeling in a long and winding tunnel, he reached the very
end of it which happened to be the main water gate of La Mesa Dam, thereby
cutting short his trip from Cavite to Fairview. After which Mr. X developed
fever, frequent diarrhea with blood on his stool and after 2 months of that
incident, he developed chronic granulomatous lesion.
The infective stage of Mr. X’s infection is which of the following forms?
1. Cyst
2. Trophozoite

Mr. A and B during the recent ECQ went to Gubat sa Ciudad Resort to have a drinking spree and to swim with their friends for about 2 hours. Little did they know, a concern citizen phoned the IATF and the LGU of Caloocan and reported the illegal activities being held in the resort.
