Here is the story:
Solar Conjunction: When The Sun Gets In The Way

I am a Navigation Engineer in the Mission Design and Navigation section at the Jet Propulsion Laboratory in Pasadena, California. As a Mars Reconnaissance Orbiter Navigator, my job is to determine where the spacecraft is (orbit determination) and where it is going (orbit prediction). I also keep the spacecraft on course by performing propulsive burns using the spacecraft engines.

The Earth and Mars both orbit the sun. Because Mars is farther away from the sun than is the Earth, the length of a Mars year is longer than the length of an Earth year (1 Mars year is about 1.9 Earth years). These different orbit periods cause the Earth and Mars to sometimes be on opposite sides of the solar system from one another. This event is called Solar Conjunction.

During Solar Conjunction, radio signals transmitted by the Deep Space Network to the Mars Reconnaissance spacecraft (and vice versa) must pass through the solar corona. Due to signal interference, the measurements that the Navigation team use for orbit determination become very noisy. Noisy measurements mean that the Navigation team can't figure out exactly where the spacecraft is and where it is going. Without accurate measurements (and an accurate orbit determination solution), the Mars Reconnaissance spacecraft cannot perform precise targeted science observations. The best thing for the team to do is to "wait out" Solar Conjunction until the signal noise levels go back to normal levels (when Mars re-emerges from behind the sun). For Mars Reconnaissance Orbiter, this Solar Conjunction period starts around April 4, 2013, and lasts until May 1, 2013. During this time, science observations are suspended and we won't be receiving any new images.

But not to worry! We should be back to our normal routine in May, so stay tuned!

Answer:

There is a period of time when the Deep Space Network won't be gathering data.

Explanation:

Solar conjunction is a time at which the sun's orb obscures the Earth and mars from each other. This period prohibits the Deep Space Network to collect data. Thus, option c is correct.

Solar conjunction is a phenomenon that occurs once in two years and affects the communication channel between Earth and Mars. During this period the Earth and Mars are at the opposite ends of their orbits away from each other.

The radio signals transmitted during this period from satellites and space crafts get interfered and noisy does not allow accurate measurement and orbit determination.

Therefore, the solar conjunction inhibits the collection of the data.

We lived there for three days -- Mother and we five children, the youngest of whom was three years old. Because of the rigorous physical examination that we had to submit to, particularly of the eyes, there was this terrible anxiety that one of us might be rejected. And if one of us was, what would the rest of the family do?

Stop Wasting Food and Save the Planet

"Wasted food" is food that is unspoiled, nutritious, and wholesome but is disposed or thrown away. This food may come from cafeterias, restaurants, factories, or grocery stores. By reducing the wastage of such food, we can help the environment in many ways.
When we throw away good food, resources such as labor, gasoline, water, fertilizers, land, and energy are wasted as well. This means that by throwing away consumable food, we are throwing away helpful resources as well. Also, when good food is dumped in landfills, the nutrients in the food are not absorbed by the soil, and instead, the food rots and produces a gas called methane. Methane is a greenhouse gas that heats up the atmosphere and is one of the major causes of global warming.
Some of the ways in which we can stop the wastage of consumable food and resources is by finding ways to stop disposing of food in the first place. By donating consumable food to non-profit government organizations (NGOs), we can feed the poor and hungry and keep them from starving. Composting, which is a method of decomposition of solid waste, helps to convert food into manure that is free of chemicals. This is another way which helps to convert good food into manure that can be used in place of harmful chemical fertilizers for crops. Understanding the importance of not wasting good food and using appropriate measures to avoid wastage of food is a step toward saving our planet.

Excerpt from A Study in Scarlet
By Conan Doyle

In the year 1878 I took my degree of Doctor of Medicine of the University of London and proceeded to Netley to go through the course prescribed for surgeons in the army. Having completed my studies there, I was duly attached to the Fifth Northumberland Fusiliers as Assistant Surgeon. The regiment was stationed in India at the time, and before I could join it, the second Afghan war had broken out. On landing at Bombay, I learned that my corps had advanced through the passes and was already deep in the enemy’s country. I followed, however, with many other officers who were in the same situation as myself, and succeeded in reaching Candahar in safety, where I found my regiment, and at once entered upon my new duties. The campaign brought honors and promotion to many, but for me it had nothing but misfortune and disaster. I was removed from my brigade and attached to the Berkshires, with whom I served at the fatal battle of Maiwand. There I was struck on the shoulder by a Jezail bullet, which shattered the bone and grazed the subclavian artery. I should have fallen into the hands of the murderous Ghazis had it not been for the devotion and courage shown by Murray, my orderly, who threw me across a pack-horse, and succeeded in bringing me safely to the British lines. Worn with pain, and weak from the prolonged hardships which I had undergone, I was removed, with a great train of wounded sufferers, to the base hospital at Peshawar. Here I rallied, and had already improved so far as to be able to walk about the wards, and even to bask a little upon the verandah, when I was struck down by enteric fever. For months my life was despaired of, and when at last I came to myself and became convalescent, I was so weak and emaciated that a medical board determined that not a day should be lost in sending me back to England. I was dispatched, accordingly, in the troopship “Orontes,” and landed a month later on Portsmouth jetty, with my health irretrievably ruined.

excerpt adapted from
Heart of Darkness
by Joseph Conrad

Going up that river was like traveling back to the earliest beginnings of the world when vegetation rioted on the earth and the big trees were kings. An empty stream, a great silence, a dense forest. The air was warm, thick, heavy, sluggish. There was no joy in the brilliance of sunshine. The long stretches of the waterway ran on, deserted, into the gloom of overshadowed distances. On silvery sand-banks hippos and alligators sunned themselves side by side. The broadening waters flowed through a mob of wooded islands; you lost your way on that river as you would in a desert, and butted all day long against sand banks, trying to find the channel, till you thought yourself bewitched and cut off for ever from everything you had known once—somewhere—far away—in another existence perhaps.
