Input: Article: On 11 March 1978, a PLO guerilla raid from Lebanon led to the Coastal Road Massacre. Israel responded by launching an invasion of southern Lebanon to destroy the PLO bases south of the Litani River. Most PLO fighters withdrew, but Israel was able to secure southern Lebanon until a UN force and the Lebanese army could take over. The PLO soon resumed its policy of attacks against Israel. In the next few years, the PLO infiltrated the south and kept up a sporadic shelling across the border. Israel carried out numerous retaliatory attacks by air and on the ground.

Now answer this question: Who secured southern Lebanon?

Output: Israel

Input: Article: In 1799, English Freemasonry almost came to a halt due to Parliamentary proclamation. In the wake of the French Revolution, the Unlawful Societies Act 1799 banned any meetings of groups that required their members to take an oath or obligation. The Grand Masters of both the Moderns and the Antients Grand Lodges called on Prime Minister William Pitt (who was not a Freemason) and explained to him that Freemasonry was a supporter of the law and lawfully constituted authority and was much involved in charitable work. As a result, Freemasonry was specifically exempted from the terms of the Act, provided that each private lodge's Secretary placed with the local "Clerk of the Peace" a list of the members of his lodge once a year. This continued until 1967 when the obligation of the provision was rescinded by Parliament.

Now answer this question: When was the Unlawful Socities Act implemented?

Output: 1799

Input: Article: Model plants such as Arabidopsis thaliana are used for studying the molecular biology of plant cells and the chloroplast. Ideally, these organisms have small genomes that are well known or completely sequenced, small stature and short generation times. Corn has been used to study mechanisms of photosynthesis and phloem loading of sugar in C4 plants. The single celled green alga Chlamydomonas reinhardtii, while not an embryophyte itself, contains a green-pigmented chloroplast related to that of land plants, making it useful for study. A red alga Cyanidioschyzon merolae has also been used to study some basic chloroplast functions. Spinach, peas, soybeans and a moss Physcomitrella patens are commonly used to study plant cell biology.

Now answer this question: What mechanism can be studied through chromosome sequencing?

Output:
photosynthesis
